v4l: fixed some issues for v4l codec. [1/1]

PD#SWPL-5313

Problem:
Decoder V4L2 interface Phase3(AFBC&MMU Support)

Solution:
1. fixed an issue of get/set parms abnormal.
2. fixed the issue of register vfm failed cause crash.
3. added post events for exception happend.
4. fixed profile_idc changes cause stuck.

Verify:
U212
