Kyle Evans 03d7aee8a7 subr_hints: Fix acpi unit hinting (at the very least)
The refactoring in r335479 overlooked the fact that the dynamic kenv can
also be switched to if hintmode == 0. This is problematic because the
checkmethod bits are only ever ran once, but it worked previously because
the use_kenv was a global state and the first lookup would enable it if
occurring after the dynamic environment has been setup.

Extending our local definition of use_kenv to include all non-STATIC
hintmodes as long as the dynamic_kenv is setup fixes this. We still have
potential issues if the dynamic kenv comes up while we're doing an anchored
search through the environment, but this is not much of a concern right now
because:

1.) The dynamic environment comes up super early in boot, just after kmem

2.) This is going to get rewritten to provide a safer mechanism for the
anchored searches, ensuring that we continue using the same environment
chain (dynamic env or static fallback) for all anchored search invocations

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
