BlueStore: speedup the performance of multi-replication flow by
switching the callback order in bluestore.

In Bluestore ack callback and commit callback are queued one by one in
the function "BlueStore;:_txc_finish_kv". Therefore, just only one callback
is needed to call, in order to improve performance. We do this by switching

mds: only update change_attr and btime when client sets appropriate feature flags

The kernel client lags the userland code a bit, and feature support for

new flags field in a cap request before then so it can get better fsync
performance.

When we go to update the cap fields, grab the features from the peer,
and verify that the appropriate flags are set before we apply updates
to the btime and change_attr.

Also, just have the function return early if dirty is 0, since it's
a no-op in that case, and turn the comment above the function into
an assertion.

In a later patch, we'll want to have the client set the sync flag in

We could add a second bool, but let's instead do what the kernel client
does which is to have a flags field. With that, the existing no_delay
bool becomes CHECK_CAPS_NODELAY.

We'll add other flags in subsequent patches.

For one user, this was causing OSD suicides when scrub ran because it
