mmc: tmio: Fix error handling when issuing CMD23

commit fc167daff581c01ebce8695e9618231cae3561a1 upstream.

If an error was detected when CMD23 was issued, command sequence should
be terminated with errors and CMD23 should be issued after retuning.

Fixes: 8b22c3c18be5 ("mmc: tmio: add CMD23 support")
