[pwc] Preserve user setting for another program

[Ben Lau]

In fact , only the setting of AGC is not preserved. By looking through
the source code , I found that AGC is set to auto mode inside the
pwc_video_open. Therefore , no matter what value you have picked
inside camstream, it will restore to auto mode automatically.

Becoz I need this feature for a demonstration urgently, I have fixed
it by myself. The patch is attached in my email.

(Based on the source code come with 2.6.20.6 kernel)
