hdpvr-video: cleanup signedness

From: Márton Németh <[email protected]>

The fifth parameter of usb_bulk_msg() is a pointer to signed (see <linux/usb.h>) so also call this function with pointer to signed.

This will remove the following sparse warning (see "make C=1"):
* warning: incorrect type in argument 5 (different signedness) expected int *actual_length
got unsigned int *<noident>

Thanks, I'll send a git pull request including the second patch for Mauro later today.
