Broadcom CNIC core network driver: fix mem leak on allocation failures in cnic_alloc_uio_rings()

We are leaking memory in drivers/net/cnic.c::cnic_alloc_uio_rings() if
either of the calls to dma_alloc_coherent() fail. This patch fixes it by
freeing both the memory allocated with kzalloc() and memory allocated with
previous calls to dma_alloc_coherent() when there's a failure.

Thanks to  Joe Perches <joe@perches.com>  for suggesting a better
implementation than my initial version.
