Fix a bug with dummy descriptor handling, and remove some
unused code.

From: Przemyslaw Patynowski <przemyslawx.patynowski@intel.com>

Fix memory leak caused by not handling dummy receive descriptor properly.
iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive
descriptors. Without this patch, when the hardware writes a dummy
descriptor, iavf would not free the page allocated for the previous receive
buffer. This is an unlikely event but can still happen.

[Jesse: massaged commit message]

As found by the compile option -Wunused-macros, remove these macros
that are never used by the code.
