[PATCH v2] arm64: fix missing __user in compat_vfp_set()

[Luc Van Oostenryck]

compat_vfp_set() is a helper writting some values via put_user()
and put_user() need a pointer annotated with '__user'.
The buffer used by the helper is correctly annotated with '__user'
but need to be casted to a real type before being given to
put_user().

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

Fix this by adding the missing '__user'.
