gfs2_atomic_open(): fix O_EXCL|O_CREAT handling on cold dcache
with the way fs/namei.c:do_last() had been done, ->atomic_open() instances needed to recognize the case when existing file got found with O_EXCL|O_CREAT, either by falling back to finish_no_open() or failing themselves. gfs2 one didn't. Fixes: 6d4ade986f9c (GFS2: Add atomic_open support) Cc: stable@kernel.org # v3.11 Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
