drivers/mmc/fsl_esdhc.c: reordered tests

As DATA_ERROR includes the value IRQSTAT_DTOE, a timeout error
would yield the first error return instead of TIMEOUT.
By swapping the test TIMEOUTs are reported as such

An alternate solution would be to remove the IRQSTAT_DTOE from the DATA_ERROR define
but as that one might be less desired I've opted for the simplest solution
