mmc: block: reduce the block timeout to 30 secs
After completion of block write request, MMC block driver waits for the
card to come out of the programming state. If card doesn't come out of
the programming state in 10 mins, it would be considered as error
condition and card would reinitialized. But this 10 mins is just too huge
and if card is continuously stuck in programming state for 10 mins,
mmcqd thread would take increase the CPU load significantly as we are
continuously polling for the card status (by sending status commands).
This patch reduces this timeout from 10 mins to 30 secs which is quite
reasonable for all well-behaved cards.
