pci: Expose a VF's owning PF to bus subclasses
ofw_pcibus now uses pci_iov_get_pf() to inherit PF locality for
VFs, but the accessor was inadvertently left in an uncommited ACPI
change. This breaks powerpc builds.
Expose the accessor from the PCI core and provide a stub when PCI_IOV
is omitted. Record VF ownership before pci_add_child() so child added
callbacks can safely query it, and remove the later redundant
assignment.

e1000: Limit the TSO sentinel to lem(4) controllers
The TSO workaround splits the final DMA segment to create a four byte
sentinel descriptor. Intel documents the premature descriptor writeback
erratum and this workaround in the 82540EP and 82545GM specification
updates (erratum 3) and the 82546GB specification update (erratum 1).
Limit the workaround and its preceding TSO state to the legacy PCI and
PCI-X controllers so PCIe controllers retain their natural descriptor
layout using one fewer descriptor per TSO packet, no split of the final
segment, and one less four byte DMA.

dounmount(): generalize comment on covered vnode lock recursion
The need for recursion applies (in somewhat different form) to both
nullfs and unionfs, and would likely apply to any other hypothetical
stacked filesystem as well.

unionfs_lock(): eliminate LK_CANRECURSE special-case
As of commit 9f5c4ef328 ("dounmount(9): temporarily enable recursion
for the covered vnode lock"), the unmount path handles recursion
automatically, so there's no longer a need to handle this case
in unionfs-specific code.

unionfs7.sh: eliminate stderr redirection
The bash-ism here results in an "ambiguous output redirect"
error when run under tcsh. Similar unionfs stress2 tests don't
do this, and unionfs7 doesn't seem to generate spurious output
when run locally, so just delete it.
