46ae5568fa lib:ldb: do not offset against NULL pointer in ldb_ldif_read()
Fix the following error observed running samba.test.registry
compiled with clang-17 and UBsan:

lib/ldb/common/ldb_ldif.c:881:9: runtime error: applying non-zero offset 137438953440 to null pointer
    #0 0x7faa0eb3932f in ldb_ldif_read lib/ldb/common/ldb_ldif.c:881

    [... a lot of Python calls skipped...]

I.e. number of elements should be checked against zero
before making an attempt to access an element by index.
