Justin Tee c0d6071aa2 scsi: lpfc: Fix lockdep warning for rx_monitor lock when unloading driver 
Lockdep enabled kernels report a theoretical deadlock state where the
cmf_timer interrupt occurs while the rx_monitor ring is being destroyed.

During rmmod, the cmf_timer is cancelled prior to the
lpfc_rx_monitor_destroy_ring call.  This actually eliminates the need to
take the rx_monitor ring lock in lpfc_rx_monitor_destroy_ring.  Thus, just
remove lock/unlock of rx_monitor in lpfc_rx_monitor_destroy_ring.
