significant clean up and optimizations: - don't call bioq_disksort() on every command, the hardware will do that for us. - remove all of the complicated bio deferral code. bio's that can't be serviced immediately can just wait on the bioq. - Only reserve one command object for doing control commands to the card. This simplifies a lot of code and significantly reduces the size of the command struct. - Allocate commands out of a slab instead of embedding them into the softc. - Call the command action method directly instead of having ips_get_free_cmd() call it indirectly.
