dcache-bulk: fix type error in updateCounts

Motivation:

master@b6bbfccbe4795568e46fc1bb1b379adf8e2de8ea https://rb.dcache.org/r/13766/
botched the fix for sql injection in the method which inserts
the updated counts.

Modification:

Fix it.

Result:

The updates appear in the table and are reported by
`info()` instead of throwing an invisible error and
remaining `0`.
