media: uvcvideo: Improve error logging in uvc_query_ctrl()

Browse source

Standard use of the driver may result in error messages on the kernel
log. This can hide other more important messages, and alert
unnecessarily the user. Let's keep dev_err() for the important
occasions.

If __uvc_query_ctrl() failed with a non -EPIPE error, then report that
with dev_err. If an error code is obtained, then report that with
dev_dbg.
