ARM: 6050/1: VFP: fix the SMP versions of vfp_{sync,flush}_hwstate
From: Imre Deak <imre.deak@nokia.com>
Recently the UP versions of these functions were refactored and as
a side effect it became possible to call them for the current thread.
This isn't true for the SMP versions however, so fix this up.
