glusterd: suppress spurious error message during startup

From glusterd log:
----------
E [glusterd-store.c:1981:glusterd_store_retrieve_volume] 0-: Unknown key:
brick-0
----------

The message is emitted from glusterd_store_retrieve_volume() when it reads the
volinfo file because it doesn't do anything with the key-value pair. Suppress the
error. The key is needed by glusterd_store_retrieve_bricks() which anyway
re-reads it.

Also change the log level to WARNING since we do not error out if an unknown key
is got while parsing the volinfo file.
