ext4: fix memory leak in xattr
commit 6e4ea8e33b2057b85d75175dd89b93f5e26de3bc upstream.
If we take the 2nd retry path in ext4_expand_extra_isize_ea, we
potentionally return from the function without having freed these
allocations. If we don't do the return, we over-write the previous
allocation pointers, so we leak either way.
Spotted with Coverity.
[ Fixed by tytso to set is and bs to NULL after freeing these
pointers, in case in the retry loop we later end up triggering an
error causing a jump to cleanup, at which point we could have a double
free bug. -- Ted ]
