[SCSI] aic79xx bus reset update
As James B. correctly noted, ahd_reset_channel() in
ahd_linux_bus_reset() should be protected by ahd_lock(). However, the
main reason for not doing so was a deadlock with the interesting
polling mechanism to detect the end a bus reset.
This patch replaces the polling mechanism with a saner signalling via
flags; it also gives us the benefit of detecting any multiple calls to
ahd_reset_channel().
