ixgbe: fix use of uninitialized padding
[ Upstream commit dcfd6b839c998bc9838e2a47f44f37afbdf3099c ]
This patch is resolving Coverity hits where padding in a structure could
be used uninitialized.
- Initialize fwd_cmd.pad/2 before ixgbe_calculate_checksum()
- Initialize buffer.pad2/3 before ixgbe_hic_unlocked()
