[media] gspca: Fix underflow in vidioc_s_parm()
"n" is a user controlled integer. The code here doesn't handle the case
where "n" is negative and this causes a static checker warning.
drivers/media/usb/gspca/gspca.c:1571 vidioc_s_parm()
warn: no lower bound on 'n'
parm.capture.readbuffers is unsigned, so make n unsigned too, fixing this.
