ASoC: cs35l41: Detect CSPL errors when sending CSPL commands

The existing code checks for the correct state transition after sending
a command. However, it is possible for the message box to return -1,
which indicates an error, if an error has occurred in the firmware.
We can detect if the error has occurred, and return a different error.
In addition, there is no recovering from a CSPL error, so the retry
mechanism is not needed in this case, and we can return immediately.
