[PATCH] staging: greybus: audio: Uninitialized variable in gbaudio_remove_controls()

[Dan Carpenter <dan.carpenter@oracle.com>]

The "err" variable is not meaningful so there is no need to print it.
It's uninitialized on the first iteration through the loop.

Fixes: 510e340efe0c ("staging: greybus: audio: Add helper APIs for dynamic audio modules")
