ipv4: Fix traffic triggered IPsec connections.
A recent patch removed the dst_free() on the allocated
dst_entry in ipv4_blackhole_route(). The dst_free() marked the
dst_entry as dead and added it to the gc list. I.e. it was setup
for a one time usage. As a result we may now have a blackhole
route cached at a socket on some IPsec scenarios. This makes the
connection unusable.
Fix this by marking the dst_entry directly at allocation time
as 'dead', so it is used only once.
Fixes: b838d5e1c5b6 ("ipv4: mark DST_NOGC and remove the operation of dst_free()")
