ice: Check root pointer for validity
ice_sched_get_tc_node uses pi->root without checking for NULL. Add a check to prevent NULL pointer dereference. Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
