ARM: 9425/1: vfp: Use vfp_state_hold() in vfp_support_entry().
vfp_entry() is invoked from exception handler and is fully preemptible.
It uses local_bh_disable() to remain uninterrupted while checking the
VFP state.
This is not working on PREEMPT_RT because local_bh_disable()
synchronizes the relevant section but the context remains fully
preemptible.
Use vfp_state_hold() for uninterrupted access.
