    idr: Remove idr_alloc_ext · 460488c5

    It has no more users, so remove it.  Move idr_alloc() back into idr.c,
    move the guts of idr_alloc_cmn() into idr_alloc_u32(), remove the
    wrappers around idr_get_free_cmn() and rename it to idr_get_free().
    While there is now no interface to allocate IDs larger than a u32,
    the IDR internals remain ready to handle a larger ID should a need arise.
    These changes make it possible to provide the guarantee that, if the
    nextid pointer points into the object, the object's ID will be initialised
    before a concurrent lookup can find the object.
