The original object name `state->objectName` was copied using the function
osaf_extended_name_lend(state->objectName, &objectName).
In case of long dn object, the `objectName` contained a reference to the string
which was stored in `state->objectName`, any change to `state->objectName`,
in this case it was the code line `state->objectName[DNlen] = '\0',
would impact the backup `objectName`.
As the `objectName` had been changed unintentionally to non-existing object dn,
`saImmOmAccessorGet_2` returned `SA_AIS_ERR_NOT_EXIST` unexpectedly.
With this fix, using C++ string to copy the `state->objectName` value.
Extracting parent DN, and object RDN are operating on C++ string, don't
change the original value.
