Fix memory leak in autofs

Summary

common.c create_directory
Free tofree when returning early.

Test Plan

Use clang's static analyzer, scan-build, to find the problem and later to show resolution.

An equivalent way to do this would be to call break instead of return here. I think this is the best way to fix the problem because it means that the cleanup path is equivalent.. but I would get signoff from trasz since he's the autofs developer/maintainer.

I'd prefer the "break" as well.

@trix_juniper.net: this patch never made it in to base. Could you please change the return to a break and submit an updated version of the patch, so we can commit it for you?
