[PATCH v2] Revert "fuse: Apply flags2 only when userspace set the FUSE_INIT_EXT"

[André Draszik]

From: André Draszik <andre.draszik@xxxxxxxxxx>

This reverts commit 3066ff93476c35679cb07a97cce37d9bb07632ff.

This patch breaks all existing userspace by requiring updates as
mentioned in the commit message, which is not allowed.

Revert to restore compatibility with existing userspace
implementations.
