Modified Files:
        src/sys/dev/usb: usb.h usb_subr.c

Log Message:
Introduce USB_DESCRIPTOR_SIZE (3), and fix two bugs:

 1) In usbd_find_idesc(), make sure the tables we're reading fit in the
    allocated buffer, otherwise small overflow (seen on KASAN, with
    bLength=1).
 2) Modify usbd_find_edesc(), to fix the same issues as 1).
