b43: HT-PHY: move TX fix to the separated function

On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix
function which iterates over available cores. It matches our HT-PHY code
which means it's probably also some TX fix.

Samuel Ortiz <sameo@linux.intel.com> says:

This is the first NFC pull request for 3.10.

The 2 features we have with this one are:

- An LLCP Service Name Lookup (SNL) netlink interface for querying LLCP
  service availability from user space.
  Along the way, Thierry also improved the existing SNL interface for
  aggregating SNL responses.

- An initial LLCP socket options implementation, for setting the Receive
  Window (RW) and the Maximum Information Unit Extension (MIUX) per socket.
  This is need for the LLCP validation tests.

We also have a microread MEI build failure here: I am not sending this one to
3.9 because the MEI bus code is not there yet, so it won't break for anyone

When not replied, the local LLC broadcasts NFC_EVENT_LLC_SDRES nl events for

brcmfmac: assure brcmf_txcomplete() is called in failure paths

For transmit packets the function brcmf_txcomplete() must be
called. This should be done as well when for some reason the
transmit fails to assure proper tx post processing. This patch
fixes the code paths in brcmf_usb_tx() that forgot to do so.
