dri3: Only update number of back buffers in loader_dri3_get_buffers
And only free no longer needed back buffers there as well.
We want to stick to the same back buffer throughout a frame, otherwise
we can run into various issues.
Bugzilla: https://bugs.freedesktop.org/105906
Bugzilla: https://bugs.freedesktop.org/106399
Fixes: 3160cb86aa92 "egl/x11: Re-allocate buffers if format is suboptimal"
