From: Matthieu CASTET <castet.matthieu@free.fr>
Fix possible unaligned u32 access in b43_generate_plcp_hdr().
Unaligned data is read/write with a u32 pointer instead of using the
packed structure. Some versions of gcc ignore the "packed" attribute, if the
structure element is accessed through a local pointer.
