Btrfs: optimize btrget/set/removexattr
btrfs actually stores the whole xattr name, including the prefix ondisk,
so using the generic resolver that strips off the prefix is not very
helpful. Instead do the real ondisk xattrs manually and only use the
generic resolver for synthetic xattrs like ACLs.
(Sorry Josef for guiding you towards the wrong direction here intially)
