rtlwifi: fix memory leak for USB device 

Free skb for received frames with a wrong checksum. This can happen
pretty rapidly, exhausting all memory.

This fixes a memleak (detected with kmemleak). Originally found while
using monitor mode, but it also appears during managed mode (once the
link is up).
