Hannes Reinecke 7a5096cf28 scsi: libfc: fixup 'sleeping function called from invalid context'

[ Upstream commit fa519f701d ]

fc_rport_login() will be calling mutex_lock() while running inside an
RCU-protected section, triggering the warning 'sleeping function called
from invalid context'.  To fix this we can drop the rcu functions here
altogether as the disc mutex protecting the list itself is already held,
preventing any list manipulation.
