video: do not compensation when paused [1/1]

Browse Source 
PD#SWPL-5664

Problem:
pcr not paused when netflix video non-tunnel mode pause

Solution:
do not compensation when diff between omxpts and pcr too large
Because when paused, continous compensation will lead diff
beween omxpts and pcr will alway inside pcr adjust threshold,
and pcr not set again, then pcr will increase

Verify:
verify by nts
