mmc: dw_mmc: Add locking around cmd11 timer
It is possible for the cmd11 interrupt to fire and delete the cmd11_timer before the cmd11_timer was actually setup. Let's fix this race by adding a few spinlocks. Note that the race wasn't seen in practice without adding some printk statements, but it still seems wise to fix.
