mmc: mmc_spi: fix error handling in mmc_spi_probe()
commit cf4c9d2ac1e42c7d18b921bec39486896645b714 upstream.
If mmc_add_host() fails, it doesn't need to call mmc_remove_host(),
or it will cause null-ptr-deref, because of deleting a not added
device in mmc_remove_host().
To fix this, goto label 'fail_glue_init', if mmc_add_host() fails,
and change the label 'fail_add_host' to 'fail_gpiod_request'.
Fixes: 15a0580ced08 ("mmc_spi host driver")
