Julian Wiedmann ce2e68b3c2 s390/qdio: don't release memory in qdio_setup_irq() 
commit 2e68adcd2f upstream.

Calling qdio_release_memory() on error is just plain wrong. It frees
the main qdio_irq struct, when following code still uses it.

Also, no other error path in qdio_establish() does this. So trust
callers to clean up via qdio_free() if some step of the QDIO
initialization fails.

Fixes: 779e6e1c72 ("[S390] qdio: new qdio driver.")
