This mode for displays running on evdi/udl as side effect of failed glamor_egl_init
reverse_prime_offload_mode was initialized to FALSE
After Mesa upgrade to 21.0.0 GL_RENDERER is not llvmpipe that results in successful glamor_egl_init
and reverse_prime_offload_mode enabled.
This commit is explicitly disabling reverse_prime_offload_mode for evdi and udl drivers

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
