Revert "scsi: libfc: Add WARN_ON() when deleting rports"
This reverts commit bbc0f8bd88abefb0f27998f40a073634a3a2db89.
It added a warning whose intent was to check whether the rport was still
linked into the peer list. It doesn't work as intended and gives false
positive warnings for two reasons:
1) If the rport is never linked into the peer list it will not be
considered empty since the list_head is never initialized.
2) If the rport is deleted from the peer list using list_del_rcu(), then
the list_head is in an undefined state and it is not considered empty.
