[PATCH pve-manager] cpu flags selector: fix glitches when scrolling the flags list

[Arthur Bied-Charreton]

Buffered rendering does not work well in the CPU flags grid due to the
rows' variable heights - Ext.js does not know the heights of the items
that are not in view.

This causes glitches when scrolling due to the whole view suddenly
having to be pushed down when a higher item suddenly gets into view.

Disable the buffered renderer, which fixes the glitches at the cost of
loading all rows in the DOM at the same time.

While this does fix the glitch, it does so at the cost of very long load
times when opening and closing the CPUTypeEdit component. Please test
and let me know what you think.
