qla3xxx: Remove unnecessary memset() in qla3xxx_send()
We do not need to zero out the 64 byte MAC request I/O control block. By zeroing out the control block and setting it to proper fields is redundant work. This is because in the qla3xxx_send() function we will already set the proper fields in this structure. The unused fields are not looked at by the hardware and do not need to be zeroed out.
