[PATCH v2 03/12] net/txgbe: fix reserved extra FDIR headroom

[Jiawen Wu]

Remove redundant 256KB FDIR headroom reservation. FDIR headroom was
already allocated in txgbe_fdir_configure() when FDIR is enabled, the
second reservation resulted in 256KB less available RX packet buffer than
the theoretical size.
