egl/drm: remove temporary fd variable

In all codepaths, this var ends up assigned to the struct, except one:
a cleanup codepath, where the `close()` was removed, leading to fd leaks.
Remove the temp fd and assign to the struct field directly instead.

                              dri2_display_destroy() helper")
