[PATCH for 3.10 02/16] brcmfmac: remove fifo bitfield from brcmf_skbuff_cb::if_flags

["Arend van Spriel" <arend@xxxxxxxxxxxx>]

The brcmf_skbuff_cb structure contain if_flags and htod fields. Both
have a bitfield defined to hold the fifo number. With a small code
change we get rid of the fifo bitfield in if_flags.
