drm/amdgpu/vcn: fix race condition issue for dpg unpause mode switch
Couldn't only rely on enc fence to decide switching to dpg unpaude mode.
Since a enc thread may not schedule a fence in time during multiple
threads running situation.
v3: 1. Rename enc_submission_cnt to dpg_enc_submission_cnt
2. Add dpg_enc_submission_cnt check in idle_work_handler
v4: Remove extra counter check, and reduce counter before idle
work schedule
