mmc: mxcmmc: check the return value of mxcmci_finish_data
We got a compile warning for mxcmmc,
drivers/mmc/host/mxcmmc.c: In function 'mxcmci_data_done':
drivers/mmc/host/mxcmmc.c:661:6: warning: variable 'data_error' set but
not used [-Wunused-but-set-variable]
The easiest method is to remove the data_error. But looking into
the code closely, I think we should check the return value of
mxcmci_finish_data as if it got data->error(the same as data_error),
we shouldn't try to read the response.
