pimd: vrf may be NULL from pim_cmd_lookup_vrf
The call into pim_cmd_lookup_vrf may be NULL
and dereferencing it before ensuring that the
vrf pointer is non-NULL is a good way to crash.
A crash can be initiated in pim:
eva# show ip msdp vrf NOEXIST mesh-group
vtysh: error reading from pimd: Permission denied (13)Warning: closing connection to pimd because of an I/O error!
