Subject: [PATCH] scsi: qla2xxx: remove setting of 'req' and 'rsp' parameter

cppcheck reports
[drivers/scsi/qla2xxx/qla_mid.c:594]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?
[drivers/scsi/qla2xxx/qla_mid.c:620]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?

The functions qla25xx_free_req_que and qla25xx_free_rsp_que are similar.
They free a 'req' and a 'rsp' parameter respectively.  The last statement of
both functions is setting the parameter to NULL.  This has no effect and
can be removed.
