ASoC: xilinx: Suppress second error message about reset failure in .remove()

Returning an error value in a platform remove callback results in an error
message being emitted by the platform core, but otherwise it doesn't make
a difference. If ret is != 0, there is already an error message and another
very generic doesn't add any value, so return 0 unconditionally.

This is a preparation for making platform remove callbacks return void.
