staging: brcm80211: remove assert to avoid panic since 2.6.37 kernel

The driver assumed it would receive skb packets from MAC80211 which
are not cloned. To guard this assumption an assert was placed in
the transmit routine. As of kernel 2.6.37 it turns out MAC80211 does
pass skb packets that are cloned. The assert is also not needed as
it does not lead to a failure state in our driver when the packet is
cloned. Therefore the assert can safely be removed.

This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130

  - AR9130
  - AR9132

kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.

I.e. the warning is correct. To fix the bug, serialize against the
