net: fix compile error of implicit declaration of skb_probe_transport_header
The commit 40893fd(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:
CC net/packet/af_packet.o
net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [net/packet/af_packet.o] Error 1
make[1]: *** [net/packet] Error 2
make: *** [net] Error 2
As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.
