scsi: lpfc: Prevent 'use after free' memory overwrite in nvmet LS handling Use-after-free memory overwrite detected. Problem reported by Ewan Milne at Red Hat after running lpfc target with additional memory checking enabled. Race condition when lpfc_nvmet_xmt_ls_rsp_cmp frees the ctxp memory in interrupt context before lpfc_nvmet_xmt_ls_rsp clears a field in the ctxp after successfully issuing the wqe. Remove the unnecessary ctxp write after reposting the rq buffer. The ctxp->rqb_buffer field is not checked in LS handling after the wqe is submitted.
