use PMAP_PAGE_INIT() to initialize mutex in pmap_page.
...
VM_MDPAGE_INIT() in pmap_free_pdp() had initialized pp_flags,
so it unintentionally cleared PMAP_PAGE_FLAGS_PV_TRACKED.
use PMAP_PAGE_INIT to avoid using PMAP_PAGE_FLAGS_PV_TRACKED.

Continuing to process had the unintended effect that `man` failed to find

exited with 1.
Prompted by a fish shell snippet that tried and failed to distinguish between
FreeBSD man (-p takes argument) and NetBSD man (-p no argument) by comparing
`man -p` exit code.
ok riastradh, logix (which also pointed out the manual page SYNOPSIS is
saying man -p should be used this way).

fix suspend and detach to work again - recent softintr changes made
xennet_tx_complete() not actually being called, because the call
in xennet_handler() was after IFF_RUNNING check; now it's called
directly rather than triggering softint, with updates locking it's safe

triggers notification to backend to close, leaves actual detach to
