net: rtnetlink.h -- only include linux/netdevice.h when used by the kernel
The commit below added a new helper dev_ingress_queue to cleanly obtain the
ingress queue pointer. This necessitated including 'linux/netdevice.h':

net: dynamic ingress_queue allocation
However this include triggers issues for applications in userspace
which use the rtnetlink interfaces. Commonly this requires they include
'net/if.h' and 'linux/rtnetlink.h' leading to a compiler error as below:
In file included from /usr/include/linux/netdevice.h:28:0,
from /usr/include/linux/rtnetlink.h:9,
from t.c:2:
/usr/include/linux/if.h:135:8: error: redefinition of ‘struct ifmap’
/usr/include/net/if.h:112:8: note: originally defined here
/usr/include/linux/if.h:169:8: error: redefinition of ‘struct ifreq’

/usr/include/linux/if.h:218:8: error: redefinition of ‘struct ifconf’
/usr/include/net/if.h:177:8: note: originally defined here
The new helper is only defined for the kernel and protected by __KERNEL__
therefore we can simply pull the include down into the same protected
section.
