Subject: [PATCH iproute2] devlink: require resource parameters

If devlink resource set parameters are not provided it crashes:
$ devlink resource set netdevsim/netdevsim0
Segmentation fault (core dumped)

This is because even though DL_OPT_RESOURCE_PATH and
DL_OPT_RESOURCE_SIZE are passed as o_required, the validation
table doesn't contain a relevant string.

Fixes: 8cd644095842 ("devlink: Add support for devlink resource abstraction")
