[PATCH] mmc: check the return value of mmc_select_mode_and_width()

[Masahiro Yamada]

Since commit 01298da31d92 ("mmc: Change mode when switching to a boot
partition"), errors in mmc_select_mode_and_width() are ignored.
The return value should be checked.

Fixes: 01298da31d92 ("mmc: Change mode when switching to a boot partition")
