gfs2: don't return ENODATA in __gfs2_xattr_set unless replacing
The function __gfs2_xattr_set() will return -ENODATA when called to
remove a xattr that does not exist. The result is that setfacl will
show an exit status of 1 when called to set only a file's mode bits
(on a file with no ACLs), despite succeeding. A "No data available"
error will be printed as well.
To fix this return 0 instead, except when the XATTR_REPLACE flag is
set, in which case -ENODATA is appropriate. This is consistent with
how most other xattr setting functions work, in other filesystems.
