During rmmod testing, messages appeared indicating lpfc_mbuf_pool entries were still busy. This situation was only seen doing rmmod after at least 1 vport (NPIV) instance was created and destroyed. The number of messages scaled with the number of vports created. When a vport is created, it can receive a PLOGI from another initiator Nport. When this happens, the driver prepares to ack the PLOGI and prepares an RPI for registration (via mbx cmd) which includes an mbuf allocation. During the unsolicited PLOGI processing and after the RPI preparation, the driver recognizes it is one of the vport instances and decides to reject the PLOGI. During the LS_RJT preparation for the PLOGI, the mailbox struct allocated for RPI registration is freed, but the mbuf that was also allocated is not released. Fix by freeing the mbuf with the mailbox struct in the LS_RJT path. As part of the code review to figure the issue out a couple of other areas where found that also would not have released the mbuf. Those are cleaned up as well.
