ken 555e391274 Modify the changer driver so it can handle (hopefully!) changers that need 
block descriptors enabled on mode sense commands.

Basically, we try sending a mode sense with block descriptors disabled (the
previous default), and if it fails, we try sending the mode sense with
block descriptors enabled.  If that works, we note that in a runtime quirk
entry, so we don't bother disabling block descriptors again for the device.

This problem was first reported by Chris Jones <cjones@honors.montana.edu>
on one of the NetBSD lists, but I'd imagine that some FreeBSD users would
have run into it eventually as well, since our changer driver is derived
form the NetBSD changer driver.

Also, change some of the probe logic so that we do the right thing in the
case of a failure to attach.

Fix a memory leak in chgetparams().

Add a couple of inline helper functions to scsi_all.h to correctly return
the start of a mode page.
