synaptics: Clean up pending completion if touch is not suspended yet
Let the interrupt handler clean up any pending completion if
syna_dev_suspend() is not run yet.
Bug: 252698616
Test: Add a debug patch that sends a command when the device is going
to sleep but syna_dev_suspend() is not run yet and confirm
the cmd_completion is cleaned up.
