[PATCH 3.12 035/176] cdc-acm: memory leak in error case

From: Oliver Neukum <redacted>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit d908f8478a8d18e66c80a12adb27764920c1f1ca upstream.

If probe() fails not only the attributes need to be removed
but also the memory freed.
