Subject: [PATCH 4.19 107/280] bnxt_en: Fix typo in firmware message timeout logic.

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 67681d02aaa1db9044a16df4ca9c77cde1221a3e ]

The logic that polls for the firmware message response uses a shorter
sleep interval for the first few passes.  But there was a typo so it
was using the wrong counter (larger counter) for these short sleep
passes.  The result is a slightly shorter timeout period for these
firmware messages than intended.  Fix it by using the proper counter.
