dm integrity: fix flush with external metadata device
[ Upstream commit 9b5948267adc9e689da609eb61cf7ed49cae5fa8 ]
With external metadata device, flush requests are not passed down to the
data device.
Fix this by submitting the flush request in dm_integrity_flush_buffers. In
order to not degrade performance, we overlap the data device flush with
the metadata device flush.
