Details:

In timeouts.c commit 7d1c26cc0c18d02cc72f348f9189dd1c3a06bfca replaced timeout
for AUTOIP with a timeout for ACD, however the value of
LWIP_NUM_SYS_TIMEOUT_INTERNAL was not updated and still counts LWIP_AUTOIP
instead of LWIP_ACD. If user has AUTOIP disabled (or not explicitly enabled)
and DHCP enabled, then ACD gets automatically enabled too. In this case there
will be one timeout too little for lwIP and first TCP packet received causes
an assertion.

Also add LWIP_IPV6_DHCP6 to the value of LWIP_NUM_SYS_TIMEOUT_INTERNAL, as it
was also not accounted for.
