EDAC/mc: Determine mci pointer from the error descriptor
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 removes @mci from the parameter list of
edac_raw_mc_handle_error() as the mci pointer does not need to be passed
any longer.
