ARM: 8810/1: vfp: Fix wrong assignement to ufp_exc
Commit 5df7a99bdd0de4a0480320264c44c04543c29d5a upstream.
In vfp_preserve_user_clear_hwstate, ufp_exc->fpinst2 gets assigned to
itself. It should actually be hwstate->fpinst2 that gets assigned to the
ufp_exc field.
Fixes commit 3aa2df6ec2ca6bc143a65351cca4266d03a8bc41 ("ARM: 8791/1:
vfp: use __copy_to_user() when saving VFP state").
