Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.
Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

None of the new D-Bus interface cases use the bssid_part in
decompose_object_path (while the old interface ones do). As such, this
is dead code and can be removed. In addition, the P2P addition here was
pretty ugly extension. Replace these with a cleaner way of passing the
separating string (e.g., "Networks") from the caller and returning the
requested item.
In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation
persistent group case where the caller had missed the need to free the
returned values.

There are a few instances where dbus handlers test the value
of errno to test whether strtoul completes successfully.
Since strtoul does not clear errno, and there's no strong
reason to suspect that errno is already clear, it is safer
to clear it right before calling strtoul. Also, any failure
in strtoul (setting errno non-zero) should be considered a
failure.
While testing using dbus-send, I found that a malformed
network path can cause a crash due to net_id being left
NULL. We should test for this before calling strtoul
on it.
