mmc: core: Issue HPI in case the BKOPS timed out
If the BKOPS timed out, the card is probably still busy in the
R1_STATE_PRG. Rather than continue as nothing has happened and hitting and
error for the next command being sent, let's try to abort the running BKOPS
by sending a HPI command to get back into R1_STATE_TRAN.
