[PATCH 3.16.y-ckt 144/216] ceph: do_sync is never initialized

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 021b77bee210843bed1ea91b5cad58235ff9c8e5 upstream.

Probably this code was syncing a lot more often then intended because
the do_sync variable wasn't set to zero.

Fixes: c62988ec0910 ('ceph: avoid meaningless calling ceph_caps_revoking if sync_mode == WB_SYNC_ALL.')
