I applied this directly, since I decided to just commit my own "don't
use negative Opt_err" patch for the test_and_set_bit() cases, and they
kind of go together.

There's still a -1 in security/keys/encrypted-keys/encrypted.c, and
there are also three cases of "Opt_error = -1" in the security layer.

All of which look pointless and wrong, but not actively buggy, so I'll
leave them alone.
