Skip parent directory creation in mount (#4310)
A POSIX filesystem does not implicitly create parent directories when they do not exist. Directories must be explicitly created and permissions be set. This also fixes a bug where asynchronous operations would create a file in the filer before the parent directory was created. If the file was a symlink or another special type of file the directory would inherit that type and become unusable in the mounted FS.
