Dan Williams 257b17ca03 dmaengine: fail device registration if channel registration fails 
Atsushi points out:
"If alloc_percpu or kzalloc failed, chan_id does not match with its
position in device->channels list.

And above "continue" looks buggy anyway.  Keeping incomplete channels
in device->channels list looks very dangerous..."

Also, fix up leakage of idr_ref in the idr_pre_get() and channel init
fail cases.
