ARM: 8810/1: vfp: Fix wrong assignement to ufp_exc

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 3aa2df6e

 ("ARM: 8791/1:
vfp: use __copy_to_user() when saving VFP state").
