features/shard: Fix permission issues
Backport of: http://review.gluster.org/11992
This patch does the following:
* reverts commit b467af0e99b39ef708420d3f7f6696b0ca618512
* changes ownership on shards under /.shard to be root:root
* makes readv, writev, [f]truncate, rename, and unlink fops
to perform operations on files under /.shard with
frame->root->{uid,gid} as 0.
This would ensure that a [f]setattr on a sharded file
does not need to be called on all the shards associated with it.
