These 2 patches are really close and are both related to error handling
in 'rio_dma_transfer()'.
The first one fixes some resources leak in case of error.
The 2nd one fixes a test so that the corresponding error can be handled
correctly.

I've splitted this into 2 paches because the first one looks trivial to me.
But the 2nd one should require more attention, IMO. The existing error
handling was dead code because 'dma_map_sg()' can not return -EFAULT. So
this error handling code has never been executed/tested and I can't test it
myself.

  rapidio: Fix resources leak in error handling path in
    'rio_dma_transfer()'
  rapidio: Fix an error handling in 'rio_dma_transfer()'
