USB: cdc-wdm: fix race leading leading to memory corruption

commit 5c22837adca7c30b66121cf18ad3e160134268d4 upstream.

This patch fixes a race whereby a pointer to a buffer
would be overwritten while the buffer was in use leading
to a double free and a memory leak. This causes crashes.
This bug was introduced in 2.6.34
