[spice v1 2/2] display-channel: monitors config debug: add head number

[Victor Toso <victortoso@xxxxxxxxxx>]

From: Victor Toso <me@xxxxxxxxxxxxxx>

The difference is subtle but compared to what client receives, this
could help identify values set to the wrong head, e.g:

First we received:
 | display-channel.c:180:monitors_config_debug: monitors config count:2 max:4
 | display-channel.c:184:monitors_config_debug: +0+0 1015x805
 | display-channel.c:184:monitors_config_debug: +1015+0 1024x740

And then:
 | display-channel.c:180:monitors_config_debug: monitors config count:3 max:4
 | display-channel.c:184:monitors_config_debug: +0+0 1015x805
 | display-channel.c:184:monitors_config_debug: +0+0 0x0
 | display-channel.c:184:monitors_config_debug: +1015+0 1024x740

In the first debug it would be helpful to have "head 0" and "head 1",
to point out the temporary error in monitor's config message.
