ARM: 7476/1: vfp: only clear vfp state for current cpu in vfp_pm_suspend
commit a84b895a2348f0dbff31b71ddf954f70a6cde368 upstream.
vfp_pm_suspend runs on each cpu, only clear the hardware state
pointer for the current cpu. Prevents a possible crash if one
cpu clears the hw state pointer when another cpu has already
checked if it is valid.
