Subject: [PATCH V3 net-next 3/9] net: ena: add explicit casting to variables

From: Arthur Kiyanovski <akiyano@...zon.com>

This patch adds explicit casting to some implicit conversions in the ena
driver. The implicit conversions fail some of our static checkers that
search for accidental conversions in our driver.
Adding this cast won't affect the end results, and would sooth the
checkers.
