[PATCH 1/5] receive-pack: don't copy "dir" parameter

[Jeff King <peff@peff.net>]

We used to do this so could pass a mutable string to
enter_repo. But since 1c64b48 (enter_repo: do not modify
input, 2011-10-04), this is not necessary.

The resulting code is simpler, and it fixes a minor leak.

If you are wondering whether upload-pack needs the same treatment, we
already did it in 6379dd0.
