[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().
