driver: video: Reset sequence change request property only during psc handling

Browse Source 
Sequence change property would configure firmware to generate psc at every
key frame. This property is configured based on low latency settings from
the client.
For cases, when client sets low latency from 1 to 0, the hardware would
continue to run in direct mode (low latency mode). Since the sequence
change property gets disabled, there would not be psc from firmware to
change the mode to 2 stage. Hence the sequence change property to be reset
only during psc handling.
