ksmbd: quiet mdssvc RPC log spam
macOS routinely probes the mdssvc RPC pipe to check for Spotlight
search support. __rpc_method() already falls through to returning 0
(unsupported) for it via the default case, but that path also logs
"Unsupported RPC: mdssvc" via pr_err on every single probe -- which
happens often enough during normal macOS browsing/backup activity to
spam the kernel log. Add an explicit case that returns the same value
without the log line; behavior is unchanged, this only removes noise
for an expected, routine client behavior.
