[spice-gtk v2 2/2] channel-usbredir: reduce amount of #ifdef USE_USBREDIR

[Victor Toso <victortoso@xxxxxxxxxx>]

From: Victor Toso <me@xxxxxxxxxxxxxx>

Not really interesting to keep tracking what is inside or not
USE_USBREDIR on channel-usbredir itself. When usbredir is disabled,
just dummy functions are needed with spice-client.h include.

After this patch, on channel-usbredir.c, we have a single #ifdef
USE_USBREDIR and the #else block is defined in the end of the file.

This patch also adds #ifdef USE_USBREDIR for channel-usbredir-priv.h
as none those functions are defined when usbredir is disabled.
