mmc: sdhci-of-esdhc: Check for error num after setting mask



commit 40c67c29 upstream.

Because of the possible failure of the dma_supported(), the
dma_set_mask_and_coherent() may return error num.
Therefore, it should be better to check it and return the error if
fails.
And since the sdhci_setup_host() has already checked the return value of
the enable_dma, we need not check it in sdhci_resume_host() again.

Fixes: 5552d7ad ("mmc: sdhci-of-esdhc: set proper dma mask for ls104x chips")
