[PATCH] builtin-push: don't access freed transport->url

[Tay Ray Chuan <rctay89@gmail.com>]

Move the failed push message to before transport_disconnect() so that
it doesn't access transport->url after transport has been free()'d (in
transport_disconnect()).

Additionally, make the failed push message more accurate by moving it
before transport_disconnect(), so that it doesn't report errors due
to a failed disconnect.
