Stanislaw Gruszka 93c7018ec1 rt2x00usb: do not anchor rx and tx urb's 
We might kill TX or RX urb during rt2x00usb_flush_entry(), what can
cause anchor list corruption like shown below:

[ 2074.035633] WARNING: CPU: 2 PID: 14480 at lib/list_debug.c:33 __list_add+0xac/0xc0
[ 2074.035634] list_add corruption. prev->next should be next (ffff88020f362c28), but was dead000000000100. (prev=ffff8801d161bb70).

To fix do not anchor TX and RX urb's, it is not needed as during
shutdown we kill those urbs in rt2x00usb_free_entries().
