Austin Clements 2d23ece135 runtime: remove redundant locking in mcache.refill
mcache.refill acquires g.m.locks, which is pointless because the
caller itself absolutely must have done so already to prevent
ownership of mcache from shifting.

Also, mcache.refill's documentation is generally a bit out-of-date, so
this cleans this up.
