afr: Ignore gluster internal (virtual) xattrs in metadata heal check
Backport of http://review.gluster.org/#/c/15548/
Problem:
In arbiter configuration, posix-xlator in the arbiter brick always sets the
GF_CONTENT_KEY in the response dict with a value 0. If the file size on the
data bricks is more than quick-read's max-file-size (64kb default), those
bricks don't set the key. Because of this difference in the no. of dict
elements, afr triggers metadata heal in lookup code path, in turn leading to
extra lookups+inodelks.
Fix:
Changed afr dict comparison logic to ignore all virtual xattrs and the on-disk
ones that we should not be healing.
