scsi: qla2xxx: Fix unused variable warning in qla2xxx_process_purls_pkt()

When CONFIG_NVME_FC is not set, fcport is unused:

  drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2xxx_process_purls_pkt':
  drivers/scsi/qla2xxx/qla_nvme.c:1183:20: warning: unused variable 'fcport' [-Wunused-variable]
   1183 |         fc_port_t *fcport = uctx->fcport;
        |                    ^~~~~~

While this preprocessor usage could be converted to a normal if
statement to allow the compiler to always see fcport as used, it is
equally easy to just eliminate the fcport variable and use uctx->fcport
directly.
