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 3aa2df6ec2ca6bc143a65351cca4266d03a8bc41 ("ARM: 8791/1: vfp: use __copy_to_user() when saving VFP state").
