mmc: mmc_spi: Fix mmc_spi_dma_alloc() return type for !HAS_DMA
If CONFIG_NO_DMA=y (e.g. Sun-3 allmodconfig):
drivers/mmc/host/mmc_spi.c:1323:15: warning: return type defaults to ‘int’ [-Wreturn-type]
static inline mmc_spi_dma_alloc(struct mmc_spi_host *host) { return 0; }
^~~~~~~~~~~~~~~~~
Fix this by adding the missing return type.
Fixes: a395acf0f6dc6409 ("mmc: mmc_spi: Allow the driver to be built when CONFIG_HAS_DMA is unset")
