soc: qcom: spcom: return EINTR on wait interrupted 



wait_for_completion_interruptible() returns ERESTARTSYS when
the device goes to low power mode.
The SPU subsystem is shutdown on deep low power mode,
so the interrupted operation is not recoverable.
return EINTR to user space to propagate the error to the user app.
