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.
