svga: move LIST_INITHEAD(dirty_buffers) earlier in svga_context_create()

Browse source 
Fixes a crash in svga_context_flush_buffers() if we use the 'draw' module
for AA lines (when the device doesn't support that feature).  We need to
initialize this list before we setup the swtnl pieces.

Found/fixed by Charmaine Lee.
