scsi: lpfc: Fix dmabuf ptr assignment in lpfc_ct_reject_event()

Upon driver receipt of a CT cmd for type = 0xFA (Management Server) and
subtype = 0x11 (Fabric Device Management Interface), the driver is
responding with garbage CT cmd data when it should send a properly formed
RJT.

The __lpfc_prep_xmit_seq64_s4() routine was using the wrong buffer for the
reject.

Fix by converting the routine to use the buffer specified in the bde within
the wqe rather than the ill-set bmp element.
