iris: Disable compression on sharing without modifier

Browse source 
For an image created either without a modifier to share or as the
destination image to get rid of compression by re-allocation, it
should have compression disabled.

Close: https://gitlab.freedesktop.org/mesa/mesa/-/issues/13729
(Fix firefox misrendering when gfx.wayland.hdr option is true)

Backport-to: 25.2
