Omit extra warn-level log on lock failure

sjlombardo · sjlombardo · commit 1fda83fa7cad · 2026-05-07T10:43:10.000-04:00
SQLCipher already logs at INFO level when a mlock or VirtualLock
fails. Since we are already doing everything possible to avoid
mlock quotas, and there is nothing practical that can be done to
avoid them, this removes the redundant WARN level log.
