ALSA: aloop: Release cable upon open error path
commit 9685347aa0a5c2869058ca6ab79fd8e93084a67f upstream.
The aloop runtime object and its assignment in the cable are left even
when opening a substream fails. This doesn't mean any memory leak,
but it still keeps the invalid pointer that may be referred by the
another side of the cable spontaneously, which is a potential Oops
cause.
Clean up the cable assignment and the empty cable upon the error path
properly.
