Update to glusterfs 3.12.3

There is an important performance bug fix specific to NetBSD here,
which disable gfid2path by default. This features causes a huge
amount of different extended attributes to be created, and the
NetBSD implementation does not scale well with it.

In order to recover a server after the feature is disabled, stop
glusterfs daemones, disable extended attributes using extattrctl,
remove ${BRICK_ROOT}/.attribute/system/trusted.gfid2path.*
re-enable extended attributes and restart glusterfs.
