usb/net/r815x: fix cast to restricted __le32
>> drivers/net/usb/r815x.c:38:16: sparse: cast to restricted __le32
>> drivers/net/usb/r815x.c:67:15: sparse: cast to restricted __le32
>> drivers/net/usb/r815x.c:69:13: sparse: incorrect type in assignment (different base types)
drivers/net/usb/r815x.c:69:13: expected unsigned int [unsigned] [addressable] [assigned] [usertype] tmp
drivers/net/usb/r815x.c:69:13: got restricted __le32 [usertype] <noident>
