afr: make flush non-transactional
Flush is historically a transaction to ensure all previous writes
were complete. This is no longer required as write-behind has
learned to make flush a barrier operation (re: conversation w/
Avati).
Flush taking a full file lock causes VMs running on afr volumes
to stall when a migration occurs and self-heal is in progress.
Make afr_flush() a non-transactional operation.
BUG: 874045
