Each struct mci has its own error descriptor. Create a function
error_desc_to_mci() to determine the corresponding mci from an error
descriptor. This eases the parameter list of edac_raw_mc_handle_
error() as the mci pointer do not need to be passed any longer.

While at it, reorder parameters of edac_raw_mc_handle_error().
