i40e: field get conversion

Refactor the i40e driver to use FIELD_GET() for mask and shift reads,
which reduces lines of code and adds clarity of intent.

This code was generated by the following coccinelle/spatch script and
then manually repaired.

While making one of the conversions, an if() check was inverted to
return early and avoid un-necessary indentation of the remainder of the
function. In some other cases a stack variable was moved inside the
block where it was used while doing cleanups/review.

A couple places were changed to use le16_get_bits() instead of FIELD_GET
with a le16_to_cpu combination.

@get@
constant shift,mask;
metavariable type T;
expression a;

-(((T)(a) & mask) >> shift)
+FIELD_GET(mask, a)
