fs: warn about impending deprecation of mandatory locks

[ Upstream commit fdd92b64d15bc4aec973caa25899afd782402e68 ]

We've had CONFIG_MANDATORY_FILE_LOCKING since 2015 and a lot of distros
have disabled it. Warn the stragglers that still use "-o mand" that
we'll be dropping support for that mount option.
