mmc: core: stop trying to switch width when only one bit is supported

mmc_select_bus_width() will try to switch to MMC_BUS_WIDTH_4 even if
MMC_CAP_4_BIT_DATA and MMC_CAP_8_BIT_DATA are not set in host->caps.
Return as soon as possible when those flags are not set

Fixes: 577fb13199b1 (mmc: rework selection of bus speed mode)
