[PATCH] zd1211rw: zd_mac_rx isn't always called in IRQ context 

e.g.

usb 1-7: rx_urb_complete() *** first fragment ***
usb 1-7: rx_urb_complete() *** second fragment ***
drivers/net/wireless/zd1211rw/zd_mac.c:1063 ASSERT
(((current_thread_info()->preempt_count) & (((1UL << (12))-1) << ((0 +
8) + 8)))) VIOLATED!

Remove the bogus assertion, and use dev_kfree_skb_any as pointed out by
Ulrich Kunitz.
