mmc: sd: Set card state to removed upon ejection 



When the SD card is removed there's a detect
work that may or may not run immediately.
In the meantime if a request is issued, then
runtime_resume would pass without actually resuming
the card. Runtime-suspend turns-off the clocks too.

Thus writing to controller registers without resuming
causes the NOC error.

Fix this by setting the appropriate card state in resume.
