Assume kernel lock as protection for `pxd_pxis' lists and `pppx_ifs' tree.
The search in `pppx_ifs' tree has no context switch. There is no context
switch between the `pxi' free unit search and tree insertion.

Use reference counters to make `pxi' dereference safe, instead of holding
netlock. Now pppx_if_find() returns `pxi' with reference counter bumped,
and newly introduced pppx_if_rele() used for release this `pxi'.

Introduce pppx_if_find_locked() which returns `pxi' but doesn't bump

function returned data with non bumped counter.

Mark dying `pxi' by setting `pxi_ready' to null, so concurrent thread
can't receive it by pppx_if_find().

The netlock is left around modification of associated ifnet's
