Ticket 49509 - Indexing of internationalized matching rules is failing
Indexing of the internationalized matching rules tests if a
matching rule indexer handle or not a given OID.
A side effect of https://pagure.io/389-ds-base/issue/49097 is that
the returned indexing callbacks are lost.
Indeed, the indexing callbacks (and potentially others fields) were
stored in the temporary pblock that was memcpy to the provided
pblock in case of success
The fix basically restores the previous behavior but do not
memcpy pblock. It read/store the pblock fields that are
inputs/outputs of slapi_mr_indexer_create.
