[PATCH v8 1/9] net/ice/base: fix dead lock issue when getting node from ID type

[Wenjun Wu]

The function ice_sched_get_node_by_id_type needs to be called
with the scheduler lock held. However, the function
ice_sched_get_node also requests the scheduler lock.
It will cause the dead lock issue.

This patch replaces function ice_sched_get_node with
function ice_sched_find_node_by_teid to solve this problem.
