ethernet: micrel: fix some error codes

commit 3af0d554c1ce11e9d0953381ff566271f9ab81a9 upstream.

There were two issues here:
1) dma_mapping_error() return true/false but we want to return -ENOMEM
2) If dmaengine_prep_slave_sg() failed then "err" wasn't set but
   presumably that should be -ENOMEM as well.

I changed the success path to "return 0;" instead of "return ret;" for
clarity.
