[SCSI] aic7xxx: leaves timer running on init failure 

aic79xx leaves timers inserted when ahd_init() (which inserts
two timers at its very end) succeeds but ahd_pci_map_int()
fails. In this case ahd->init_level gets incremented to 5 only
when that function succeeds, but ahd_free() calls ahd_shutdown()
only when ahd->init_level == 5, and ahd_shutdown() is where the
timers get removed. Since the freeing of the IRQ is not controlled
by ahd->init_level, we should increment init_level prior to
calling ahd_pci_map_int().
