    PM / runtime: Update links_count also if !CONFIG_SRCU
    
    Commit baa8809f6097 (PM / runtime: Optimize the use of device links)
    added an invocation of pm_runtime_drop_link() to __device_link_del().
    However there are two variants of that function, one for CONFIG_SRCU and
    another for !CONFIG_SRCU, and the commit only modified the former.
