Clean up a clangalyzer warning in directory_remove_invalid

"At this point in the code, msg has been set to a string
constant. But the tor code checks that msg is not NULL, and the
redundant NULL check confuses the analyser[...] To avoid this
spurious warning, the patch initialises msg to NULL."

Patch from teor. another part of 13157.
