net: hsr: fix hsr build error when lockdep is not enabled
In hsr, lockdep_is_held() is needed for rcu_dereference_bh_check().
But if lockdep is not enabled, lockdep_is_held() causes a build error:
ERROR: modpost: "lockdep_is_held" [net/hsr/hsr.ko] undefined!
Thus, this patch solved by adding lockdep_hsr_is_held(). This helper
function calls the lockdep_is_held() when lockdep is enabled, and returns 1
if not defined.
Fixes: e7f27420681f ("net: hsr: fix suspicious RCU usage warning in hsr_node_get_first()")
