cifs: sanitize multiple delimiters in prepath
mount.cifs can pass a device with multiple delimiters in it. This will
cause rename(2) to fail with ENOENT.
V2:
- Make sanitize_path more readable.
- Fix multiple delimiters between UNC and prepath.
- Avoid a memory leak if a bad user starts putting a lot of delimiters
in the path on purpose.
