Alexander Motin 156c1ebe3b Some code reorganization. 
- Remove code duplication by adding two new functions to execute prepared
queue entry via either mbox or request queue and wait for result.
 - Since the new function executing via request queue sleeps any way, make
it sleep also in case of overflows or handle shortages.  It should make it
more reliable and less affecting other less flexible request queue users.
 - Turn isp_target_put_entry() into not target-specific isp_send_entry().
 - Make handling of responses with control handles more universal.
 - Move RQSTYPE_RPT_ID_ACQ handling into new function.
 - Inline isp_handle_other_response(), becoming trivial after above.
 - Clean the list of IOCBs from pre-24xx ones.

/*
* The Qlogic driver gets an interrupt to look at response queue entries.
* Some of these are status completions for initiatior mode commands, but
* if target mode is enabled, we get a whole wad of response queue entries
* to be handled here.
*
* Basically the split into 3 main groups: Lun Enable/Modification responses,
* SCSI Command processing, and Immediate Notification events.
*
* You start by writing a request queue entry to enable target mode (and
* establish some resource limitations which you can modify later).
* The f/w responds with a LUN ENABLE or LUN MODIFY response with
* the status of this action. If the enable was successful, you can expect...
*
* Response queue entries with SCSI commands encapsulate show up in an ATIO
* (Accept Target IO) type- sometimes with enough info to stop the command at
* this level. Ultimately the driver has to feed back to the f/w's request
* queue a sequence of CTIOs (continue target I/O) that describe data to
* be moved and/or status to be sent) and finally finishing with sending
* to the f/w's response queue an ATIO which then completes the handshake
* with the f/w for that command. There's a lot of variations on this theme,
* including flags you can set in the CTIO for the Qlogic 2X00 fibre channel
* cards that 'auto-replenish' the f/w's ATIO count, but this is the basic
* gist of it.
*
* The third group that can show up in the response queue are Immediate
* Notification events. These include things like notifications of SCSI bus
* resets, or Bus Device Reset messages or other messages received. This
* a classic oddbins area. It can get a little weird because you then turn
* around and acknowledge the Immediate Notify by writing an entry onto the
* request queue and then the f/w turns around and gives you an acknowledgement
* to *your* acknowledgement on the response queue (the idea being to let
* the f/w tell you when the event is *really* over I guess).
*
*/
/*
* A new response queue entry has arrived. The interrupt service code
* has already swizzled it into the platform dependent from canonical form.
*
* Because of the way this driver is designed, unfortunately most of the
* actual synchronization work has to be done in the platform specific
* code- we have no synchroniation primitives in the common code.
