description:
use ALIGNED_POINTER() instead of ALIGN().
The type of ALIGN() is vary on architecture and casting pointer to u_int
is incorrect for MI code.
Since the code is to make sure aligned access to IP header and requires
bcopy if the test fails.  So the performance implication is not necessary
and we can use ALIGNED_POINTER() here.
