rt2x00: Remove duplicate deinitialization
When rt2x00queue_alloc_rxskbs() fails rt2x00queue_unitialize() will be called which will free all rxskb. So we don't need to do this in the rt2x00queue_alloc_rxskb() function as well. rt2x00queue_free_skb() unmaps the DMA but doesn't clear the allocation flag. Since the code is copied from rt2x00queue_unmap_skb() anyway (and that function does clear the flag) we might as well use that function directly.
