Subject: [PATCH net-next 10/14] mlxsw: spectrum_router: Break nexthop group entry validation to a separate function

From: Ido Schimmel <idosch@...dia.com>

The validation of a nexthop group entry is also necessary for resilient
nexthop groups, so break the validation to a separate function to allow
for code reuse in subsequent patches.
