[PATCH] hexagon: correct type on pgd copy

[Ilia Mirkin <imirkin@alum.mit.edu>]

swapper_pg_dir is an array of pgd_t, not pgd_t*. This has no actual
effect since sizeof(pgd_t) == sizeof(pgd_t*), but unconfuses tools that
check types.

Looks like I wrote this ~2 years ago, when I was playing around with spatch,
but forgot to send it out (along with a few other patches which no longer
applied). This still seems valid though.
