Konstantin Kharlamov 275cf62e20 loader/dri3: temporarily work around a crash when front is NULL ...

Commit c65bde7b1e introduced a regression where under certain
circumstances `front` may be NULL, thus leading to a crash. It's not
currently known what exactly causes `front` to become NULL, nor we can
revert the offending commit, because there had been too many unrelated
changes that now depend on this commit.

So until someone comes up with a proper fix, let's add a workaround so
instead of crashing we just return from the function early.

This commit was tested with the bug `8982` and helps with the crash
with no other noticeable problems.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/8982
Fixes: c65bde7b1e ("frontend/dri: inline __DRIdrawable in dri_drawable, make __DRIdrawable opaque")
