This patch removes the CONFIG_MCORE2 check from around NET_IP_ALIGN.  It is
based on a suggestion from Andi Kleen.  The assumption is that there are
not any x86 cores where unaligned access is really slow, and this change
would allow for a performance improvement to still exist on configurations
that are not necessarily optimized for Core 2.
