scsi: qla2xxx: Suppress a Coveritiy complaint about integer overflow
This patch fixes the following Coverity complaint:
Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression dma_eng_num *
65536U with type unsigned int (32 bits, unsigned) is evaluated using 32-bit
arithmetic, and then used in a context that expects an expression of type
uint64_t (64 bits, unsigned).
