xfs: convert pag_ici_lock to a spin lock now that we are using RCU protection for the inode cache lookups, the lock is only needed on the modification side. Hence it is not necessary for the lock to be a rwlock as there are no read side holders anymore. Convert it to a spin lock to reflect it's exclusive nature.
