[PATCH 1/2] scsi: aic7xxx: Fix potential critical section table leak

[Guangshuo Li]

ahc_loadseq() allocates a critical section table, but ahc_free()
does not release it. Free the table after shutting down the
controller and releasing its platform resources.

This issue was found by our static analysis tool under development.
