[PATCH] qla2xxx: Increase the size of struct qla_fcp_prio_cfg to FCP_PRIO_CFG_SIZE

[Bart Van Assche <bvanassche@acm.org>]

This patch fixes the following Coverity complaint without changing any
functionality:

CID 337793 (#1 of 1): Wrong size argument (SIZEOF_MISMATCH)
suspicious_sizeof: Passing argument ha->fcp_prio_cfg of type
struct qla_fcp_prio_cfg * and argument 32768UL to function memset is
suspicious because a multiple of sizeof (struct qla_fcp_prio_cfg) /*48*/
is expected.

memset(ha->fcp_prio_cfg, 0, FCP_PRIO_CFG_SIZE);
