avoid sometimes expensive operations when annex.supportunlocked = false

Browse source 
This will mostly just avoid a DB lookup, so things get marginally
faster. But in cases where there are many files using the same key, it
can be a more significant speedup.

Added overhead is one MVar lookup per call, which should be small
enough, since this happens after transferring or ingesting a file,
which is always a lot more work than that. It would be nice, though,
to move getGitConfig to AnnexRead, which there is an open todo about.

used. --[[Joey]]
The easy things have been moved now, but some things like Annex.force and
Annex.fast would be good to move. Moving those would involve running
argument processing outside the Annex monad. The main reason argument
processing runs in the Annex monad is to set those values, but there may be
other reasons too, so this will be a large set of changes that need to all
happen together. --[[Joey]]
