[PATCH 10/10] accel/habanalabs: refactor abort of completions and waits

[Oded Gabbay]

From: Koby Elbaz <kelbaz at habana.ai>

Aborting CS completions should be in command_submission.c but aborting
waiting for user interrupts should be in device.c.

This separation is also for adding more abort operations in the future.
