    dm-ploop: Fix positive error code in ploop_prepare_reloc_index_wb()
    
    Later we export this error code to .message caller,
    and this is a problem, since positive return values
    are reserved.
    
    Found in scope of https://jira.sw.ru/browse/PSBM-136140
    To_merge: 93f9012782e5 ("dm-ploop: Add ploop target driver")
