scsi: FlashPoint: Remove redundant variable bm_int_st

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]
