Use wait_for_completion_timeout() instead of using a timer (as Christoph Hellwig did for aic7xxx). That lets me eliminate the sym_eh_wait structure; the struct completion, the old_done pointer and the to_do flag can be folded into the sym_ucmd (which overrides the scsi_pointer in scsi_cmnd). The sym_eh_done() function becomes much simpler as the timeout handling is done in sym_eh_handler() directly. The host_lock can be unlocked earlier, and I cache the host in a local variable to make accesses to it quicker.
