ASoC: SOF: ipc-msg-injector: Propagate write errors correctly

Browse source

This code is supposed to propagate errors from simple_write_to_buffer()
or return -EFAULT if "size != count".  However "size" needs to be signed
for the code to work correctly and the case where "size == 0" is not
handled correctly.

Fixes: 2f0b1b013b ("ASoC: SOF: debug: Add support for IPC message injection")
