[PATCH 2/6] net/i40e: reduce code indentation

[Bruce Richardson]

With the removal of the #ifdef block for 16-byte descriptor loads, the
do { } while(0) around the descriptor load block becomes unnecessary.
Removing that do-while allows us to reduce indentation level of the code
by one tab, and makes the function that little cleaner and clearer to
read.
