android: binder: Use wake up hint for synchronous transactions.

(cherry pick from 572b57fc6f7fb6ffaa979d505ec2b0a9e9840cca)

Use wake_up_interruptible_sync() to hint to the scheduler binder
transactions are synchronous wakeups. Disable preemption while waking
to avoid ping-ponging on the binder lock.
