Hans de Goede 3fe4107643 glamor: Fix crash when master gpu is using glamor and another gpu is hotplugged 
When a GPU gets hotplugged while X is already running, glamor_egl_init()
gets called and changes the current egl context, without updating
lastGLContext, potentially causing the next glamor call on another GPU to
run in the wrong context.

This causes glamor to e.g. crash in the next glamor_create_pixmap() call
(called through the master's screen->CreatePixmap), note this is not the
only troublesome entry point I've seen other backtraces when using a
compositing window manager.

Set lastGLContext to NULL to force the next glamor_make_current() call
to set the right context.

Note that we cannot use glamor_make_current() here to replace the
eglMakeCurrent() call and update lastGLContext for us because
glamor_make_current takes a glamor_priv struct as argument and that
has not been created yet when glamor_egl_init() gets called.
