MDCache::dump_cache return 1 on success.

Signed-off-by: "Yan, Zheng" <zyan@redhat.com>
(cherry picked from commit f519fca9dd958121a289676edf5175fb8be9894f)

Backport note: the original cause was commit
46c829d23aa5379a973d2330b0551a5b92598133. The fix was part of snapshot fixes
for Mimic in f519fca9dd958121a289676edf5175fb8be9894f which was not backported.
