lockdep: disable lockdep logging

When lockdep reports a locking error, it disables global
debug_locks which results in other lock debugging features
getting disabled.

Disable only lockdep logging once a locking error is reported.
This will help in tracking lock owners and their stacks from
ramdumps even when lockdep is not reporting them on console.
