[PATCH v1] exfat: fix timing of synchronizing bitmap and inode

["Yuezhang.Mo@xxxxxxxx" <Yuezhang.Mo@xxxxxxxx>]

Commit(f55c096f62f1 exfat: do not zero the extended part) changed
the timing of synchronizing bitmap and inode in exfat_cont_expand().
The change caused xfstests generic/013 to fail if 'dirsync' or 'sync'
is enabled. So this commit restores the timing.
