[ Upstream commit a277d516de5f498c91d91189717ef7e01102ad27 ]
When CONFIG_CC_OPTIMIZE_FOR_DEBUGGING is enabled, the compiler
fails to optimize out a dead code path, which leads to a link failure:
net/openvswitch/conntrack.o: In function `ovs_ct_set_labels':
conntrack.c:(.text+0x2e60): undefined reference to `nf_connlabels_replace'
In this configuration, we can take a shortcut, and completely
remove the contrack label code. This may also help the regular
optimization.
