iavf: field prep conversion
Refactor iavf driver to use FIELD_PREP(), which reduces lines of code
and adds clarity of intent.
This code was generated by the following coccinelle/spatch script and
then manually repaired.
Clean up a couple spots in the code that had repetitive
y = cpu_to_*((blah << blah_blah) & blat)
y |= cpu_to_*((blahs << blahs_blahs) & blats)
to
x = FIELD_PREP(blat blah)
x |= FIELD_PREP(blats, blahs)
y = cpu_to_*(x);
