Subject: [net-next 12/12] ixgbe: fix broken ipsec Rx with proper cast on spi

From: Shannon Nelson <shannon.nelson@...cle.com>

Fix up a cast problem introduced by a sparse cleanup patch.  This fixes
a problem where the encrypted packets were not recognized on Rx and
subsequently dropped.

Fixes: 9cfbfa701b55 ("ixgbe: cleanup sparse warnings")
