[PATCH v2 2/3] ath10k: Don't try un-supported idle_ps_config command.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

The warning the the logs does not give user a clue as to what
command is failing, so it is worth it to check for un-supported
command before trying the call.

And add return-code to survey error message.
