usb: potential integer overflow in usbg_make_tpg()
The variable tpgt in usbg_make_tpg() is defined as unsigned long and is
assigned to tpgt->tport_tpgt, which is defined as u16. This may cause an
integer overflow when tpgt is greater than USHRT_MAX (65535). I
haven't tried to trigger it myself, but it is possible to trigger it
by calling usbg_make_tpg() with a large value for tpgt.
I modified the type of tpgt to match tpgt->tport_tpgt and adjusted the
relevant code accordingly.
This patch is similar to commit 59c816c1f24d ("vhost/scsi: potential
memory corruption").
