qxl: Fix uninitialised struct field head.surface_id

Browse Source 
commit 738acd49eb018feb873e0fac8f9517493f6ce2c7 upstream.

The surface_id struct field in head is not being initialized and
static analysis warns that this is being passed through to
dev->monitors_config->heads[i] on an assignment. Clear up this
warning by initializing it to zero.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: a6d3c4d79822 ("qxl: hook monitors_config updates into crtc, not encoder.")
