call ospm_power_suspend() in case gfx device isn't suspended

We see cases that gfx device isn't suspended when system suspend
process come into gfx_suspend(), so it need to check gfx suspend
state and call ospm_power_suspend() to suspend device properly.
Otherwise we would see performance downgrade in video decoding/encoding
if system is suspened once.
