bcachefs: Set the last mount time using the realtime clock
This way the last mount time is actually meaningful instead of just being various times from 1970 (which happens with the monotonic clock). Also, roundup_pow_of_two() is undefined when passed in 0, so check before calling it. Signed-off-by: Tim Schlueter <schlueter.tim@linux.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
