CRAS: Use client removal path when reattach fails.
CRAS: Use client removal path when reattach fails.

Instead of freeing the stream when reattach fails, go through the normal
stream removal path.  This will leave everything safe if the client
later calls rm_stream on the stream that failed to reattach.

BUG=none.
TEST=Run cras and re-attach streams, best way to get a failure is to get
the system to run out or memory or file descriptors.
