Fix debug regression in video/pwc

Commit 85237f202d46d55c1bffe0c5b1aa3ddc0f1dce4d introduced the
following warning:
drivers/media/video/pwc/pwc-if.c: In function "pwc_video_close":
drivers/media/video/pwc/pwc-if.c:1211: warning: "i" may be used uninitialized in this function

This is true, and can cause a broken debug message to be logged.
Here's a fix.

Fix is already in Linus' tree for 2.6.23:
