pimd: There exists a path where on vrf bringup we do not create the pimreg
When creating configuration for a vrf *Before* the vrf has been created, pim will not properly create the pimreg device and we will promptly crash when we try to pass data. Put some code checks in place to ensure that the pimreg is created for vrf's. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
