Stefan Roesch 19f4e16366 fs: split off setxattr_copy and do_setxattr function from setxattr ...

[ Upstream commit 1a91794ce8481a293c5ef432feb440aee1455619 ]

This splits of the setup part of the function setxattr in its own
dedicated function called setxattr_copy. In addition it also exposes a new
function called do_setxattr for making the setxattr call.

This makes it possible to call these two functions from io_uring in the
processing of an xattr request.
