cifscreds: add a check and warnings for session keyring problems
Many distros do not call into pam_keyinit to set up the session keyring
properly at login time. When cifscreds add is used in such a session,
the kernel will spawn a new session keyring in which to install the
credentials. That keyring will then go away once the cifscreds process
exits.
Check for this situation by looking to see if the session and
user-session keyrings are the same. Throw a warning if so, and add some
verbiage to the cifscreds manpage that explains the issue. Also, if
the session keyring can't be queried for any reason, then cause the
program to error out.
