[LTP] [PATCH 1/2] nsproxy: restore EINVAL for non-namespace file descriptor

The LTP testsuite reported a regression where users would now see EBADF
returned instead of EINVAL when an fd was passed that referred to an open
file but the file was not a nsfd. Fix this by continuing to report EINVAL.

I plan on sending this to Linus once it has sat in for-next for a few
days.
