[PATCH] scsi: ibmvfc: Fix use of uninitialized rport in ibmvfc_do_work()

[PATCH] scsi: ibmvfc: Fix use of uninitialized rport in ibmvfc_do_work()

[Nathan Chancellor]

After commit 696d1cc2aaa2 ("scsi: ibmvfc: process NVMe/FC rports in work
thread"), clang warns (or errors with CONFIG_WERROR=y / W=e):

  drivers/scsi/ibmvscsi/ibmvfc-core.c:6154:15: error: variable 'rport' is uninitialized when used here [-Werror,-Wuninitialized]
   6154 |                         } else if (rport && tgt->action == IBMVFC_TGT_ACTION_DEL_AND_LOGOUT_RPORT) {
        |                                    ^~~~~

The check for rport is unnecessary in this block, it was accidentally
included from copying and pasting. Remove it to clear up the warning.
