glusterd: harden 'volume start' staging to check for brick dirs' presence

PROBLEM:

When the brick directory of a volume is absent on any of the servers,
AND an attempt is made to start the volume, commit fails ONLY on the
node where the brick dir is absent, leading to a split-brain like
situation.

FIX:

Harden 'volume start' to check for the presence of brick directories
at the time of staging, thereby preventing commit failure.
