[PATCH 03/13] ovl: ovl_check_setxattr() get rid of redundant -EOPNOTSUPP check

[Vivek Goyal <vgoyal@redhat.com>]

At mount time we check if upper supports xattr or not and set ofs->noxattr
field accordingly. But in ovl_check_setxattr() still seems to have logic
which expects that ovl_do_setxattr() can return -EOPNOTSUPP. Not sure when
and how can we hit this code. Feels redundant to me. So I am removing
this code.
