In net/Kconfig, NET_DEVLINK implies NET_DROP_MONITOR.
The original behavior of the 'imply' keyword prevents NET_DROP_MONITOR from being 'm' when NET_DEVLINK=y.
With the planned Kconfig change that relaxes the 'imply', the combination of NET_DEVLINK=y and NET_DROP_MONITOR=m would be allowed.
Use IS_REACHABLE() to avoid the vmlinux link error for this case.

This build error was reported in linux-next. https://lkml.org/lkml/2020/3/10/1936
If this patch is acceptable, I'd like to get Ack from the maintainers, and insert this patch before my Kconfig change.
