KEYS: Propagate error code instead of returning -EINVAL
This is from a Smatch check I'm writing.
strncpy_from_user() returns -EFAULT on error so the first change just
silences a warning but doesn't change how the code works.
The other change is a bug fix because install_thread_keyring_to_cred()
can return a variety of errors such as -EINVAL, -EEXIST, -ENOMEM or
-EKEYREVOKED.
