Bug 32990: Prevent deadlock in _update_batch_record_counts

Resolves:
C4::ImportBatch::_update_batch_record_counts(): DBI Exception: DBD::mysql::st
execute failed: Deadlock found when trying to get lock; try restarting
transaction at /usr/share/koha/C4/ImportBatch.pm line 392

See also bug 32558.

Test plan:
If you apply 32558 first, run multiple processes that stage a marc import.
Without this patch, you can trigger the deadlock.
With this patch, it works.
