Thiago Rafael Becker a31080899d 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.

Fixes: 24e0a1eff9e2 ("cifs: switch to new mount api")
