ARM: 8791/1: vfp: use __copy_to_user() when saving VFP state
Commit 3aa2df6ec2ca6bc143a65351cca4266d03a8bc41 upstream.
Use __copy_to_user() rather than __put_user_error() for individual
members when saving VFP state.
This has the benefit of disabling/enabling PAN once per copied struct
intead of once per write.
