    nimble/ll: Add null check before removing scheduled conn request
    
    The connection request cancel function could attempt to remove a
    scheduler element even when no connection state machine was assigned.
    
    To prevent this, a null check was added before removing the scheduler
    element. If no connection state machine is present, the function now
    returns early.
    
    This change prevents potential crashes when the controller attempts
    to clean up after failed connection creation.
