[client] egl: fix non-DMA font atlas corruption

Browse Source 
Unbind the streamed desktop pixel upload buffer before ImGui processes
CPU-backed font atlas updates.

This prevents atlas pointers from being interpreted as PBO offsets when
DMA is disabled, which caused newly requested glyphs to be missing.
