scsi: bnx2fc: fix incorrect cast to u64 on shift operation
[ Upstream commit d0c0d902339249c75da85fd9257a86cbb98dfaa5 ]
Currently an int is being shifted and the result is being cast to a u64
which leads to undefined behaviour if the shift is more than 31 bits. Fix
this by casting the integer value 1 to u64 before the shift operation.
Addresses-Coverity: ("Bad shift operation")
Fixes: 7b594769120b ("[SCSI] bnx2fc: Handle REC_TOV error code from firmware")
