[COMMON] media: mfc: avoid the kernel panic in specific scenario

We do not support DRC(Dynamic Resolution Change)
and seeking overlapped scenario.
However, in this case, we avoid the kernel panic.

wait_state is changed as below.
DRC detected -> WAIT_DECODING -> g_fmt -> WAIT_DPB_FLUSH
-> stramoff(dst) -> WAIT_NONE -> decoding(INIT_BUF, NAL_START)
