cxl/hdm: Fail upon detecting 0-sized decoders
Decoders committed with 0-size lead to later crashes on shutdown as
__cxl_dpa_release() assumes a 'struct resource' has been established in
the in 'cxlds->dpa_res'. Just fail the driver load in this instance
since there are deeper problems with the enumeration or the setup when
this happens.
