PATCH 1/2 : block/DAC960: remove sleep_on*() usage

From: Nishanth Aravamudan <[email protected]>

Use wait_event_interruptible_timeout() instead of the deprecated interruptible_sleep_on_timeout(). The existing code is complicated in the conditional and so is the new code. Also replace sleep_on_timeout() with direct wait-queue usage. Patch is compile-tested.
