ethoc: use devres resource management

Browse source 
The point of using the devres resource management routines is that they
simplify the driver by taking care of releasing resources on failure and
release.  A recent commit added a bunch of error handling that is unnecessary
in this context.

This patch removes this redundant error handling, as well as using
dmam_alloc_coherent in place of dma_alloc_coherent in order to use this
framework consistenly throughout the driver.
