Since not all listeners (i.e VirtualConsoles) of GL events have
a valid EGL context, make sure that there is a valid context
before making EGL calls.
This fixes the following crash seen while launching the VM with
"-device virtio-gpu-pci,max_outputs=1,blob=true -display gtk,gl=on"
No provider of eglCreateImageKHR found. Requires one of:
EGL_KHR_image
EGL_KHR_image_base
Fixes: 7cc712e9862ff ("ui: dispatch GL events to all listeners")
