The variable bm_int_st is assigned a value but it is never read. The
variable and the assignment are redundant and can be removed.

Cleans up clang scan build warning:
drivers/scsi/FlashPoint.c:1726:7: warning: Although the value stored
to 'bm_int_st' is used in the enclosing expression, the value is never
actually read from 'bm_int_st' [deadcode.DeadStores]
