Phil Sutter b936ec6aad netfilter: conntrack: helper: Replace -EEXIST by -EBUSY
[ Upstream commit 54416fd767 ]

The helper registration return value is passed-through by module_init
callbacks which modprobe confuses with the harmless -EEXIST returned
when trying to load an already loaded module.

Make sure modprobe fails so users notice their helper has not been
registered and won't work.
