If the sdio_enable_func() function fails on .probe, the -EIO errno code
is always returned but that could make more difficult to debug and find
the cause of why the function actually failed.

Since the driver/device core prints the value returned by .probe in its
error message propagate what was returned by sdio_enable_func() at fail.
