glusterd: volume inode/fd status broken with brick mux

        backport of:https://review.gluster.org/#/c/19846/6

Problem:
The values for inode/fd was populated from the ctx received
from the server xlator.
Without brickmux, every brick from a volume belonged to a
single brick from the volume.
So searching the server and populating it worked.

With brickmux, a number of bricks can be confined to a single
process. These bricks can be from different volumes too (if
we use the max-bricks-per-process option).
If they are from different volumes, using the server xlator
to populate causes problem.

Fix:
Use the brick to validate and populate the inode/fd status.
