Fix widget texture list locking to avoid animation issues on eglfs
QWidgetBackingStore::sync() has two variants. The widget texture list
logic was only present in one of them. This led to problems on eglfs
in cases when the other variant got invoked. (for instance using the
scroll area in the qopenglwidget example)
eglfs relies on the texture lists's lock status to properly serialize
its somewhat asynchronous built-in compositing mechanism and therefore
is the only platform affected. The patch moves the code to be invoked
from both sync() variants.
