Rebalance: Avoid setting other component's xattrs

Problem 1:
 In "gf_defrag_handle_hardlink" we used to do setxattr on internal
afr keys. Which lead to afr aborting the op saying "operation not
supported".

Solution : Sending a new xattr with only required keys.

Problem 2:
 Hardlink migration tries to create linkto files for 2nd to (n-1)th
hardlink of a file on their respective hashed_subvolumes. It may so
happen that the linkto file already exists on the hashed subvolume
may be due to an earlier lookup or hashed subvolume on the older
graph is same as that on the new graph. Hence any new link call may
fail with EEXIST.

Solution: Will log the message with DEBUG level for EEXIST . Otherwise will
log with ERROR level.
