[PATCH 05/13] rt2x00: Add unlikely to skb allocation failure check

[Ivo van Doorn <ivdoorn@gmail.com>]

From: Helmut Schaa <helmut.schaa@googlemail.com>

The skb allocation should really only fail under high memory pressure
or other uncommon situations. Hence, mark the allocation failure check
as unlikely.
