[PATCH] arm64: fix missing __user in compat_vfp_{get,set}()

[Luc Van Oostenryck]

compat_vfp_get() & compat_vfp_set() are two helpers reading
or writting some values via {get,put}_user() which need a
pointer annotated with '__user'.
The buffers used by the two helpers are correctly '__user'
annotated but need to be casted to a real type before being
given to {get,put}_user().

The problem is that this cast lack a '__user' annotation.

Fix this by adding the missing '__user'.
