Soft-pin is but one possible mechanism for pinning buffers. We're
working on another called VM_BIND. Most of the time, the real question
we're asking isn't "are we using soft-pin?" but rather "are we using
relocations?" because it's relocations, and not soft-pin, that cause us
all the extra pain we have to write code to handle. This commit flips
the majority of those checks around. The new helper is currently just
the exact inverse of the old use_softpin helper.
