localrepo: prevent wlock from being inherited when a transaction is running

Review feedback from Pierre-Yves David. A separate line of work is working to
ensure that dirstate writes are written to a separate 'pending' file while a
transaction is active. Lock inheritance currently conflicts with that, so dodge
the issue by simply preventing inheritance while a transaction is running.

Custom merge drivers aren't going to run inside a transaction, so this doesn't
affect that.
