The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vmalloc(a * b)

with:
        vmalloc(array_size(a, b))

as well as handling cases of:

        vmalloc(a * b * c)

with:

        vmalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vmalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

There is mistake in the rt_mode_allow_non_local assignment.
It should be used to check if sending to non-local addresses is
allowed, now it checks if local addresses are allowed.

As local addresses are allowed for most of the cases, the only
places that are affected are for traffic to transparent cache
servers:

- bypass connections when cache server is not available
- related ICMP in FORWARD hook when sent to cache server
