Fix an issue with the dynamic pcpu/vnet data allocators.
We cannot expect that modspace is the last entry in the linker
set and thus that modspace + possible extra space up to PAGE_SIZE
would be contiguous. For the moment do not support more than
*_MODMIN space and ignore the extra space (*).
(*) We know how to get it back but it'll need testing.
