Subject: [PATCH net-next] ipmr: Do not define MAXVIFS twice

From: David Ahern <dsahern@...il.com>

b70432f7319eb refactored mroute code to make it common between ipv4
and ipv6. In the process, MAXVIFS got defined a second time: the
first is in the uapi file linux/mroute.h. A second one was created
presumably for IPv6 but it is not needed. Remove it and have
mroute_base.h include the uapi file directly since it is shared.

include/linux/mroute.h can not be included in mroute_base.h because
it contains a reference to mr_mfc which is defined in mroute_base.h.
