Alexandre Bounine f8e3a68c05 rapidio: fix return value description for dma_prep functions 
Update return value description for rio_dma_prep_...  functions to
include error-valued pointer that can be returned by HW mport device
drivers.  Return values from these functions must be checked using
IS_ERR_OR_NULL macro.

This patch is applicable to kernel versions starting from v4.6-rc1.
