[PATCH 08/10] xfs: initialise xfssync work before running quotachecks

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

Because the mount process can run a quotacheck and consume lots of
inodes, we need to be able to run periodic inode reclaim during the
mount process. This will prevent running the system out of memory
during quota checks.

This essentially reverts 2bcf6e97, but that is safe to do now that
the quota sync code that was causing problems during long quotacheck
executions is now gone.
