fd70ca40cc OPFS VFS: change the xCheckReservedLock() impl to always return false, as discussed in [forum:a2f573b00cda1372|forum thread a2f573b00cda1372]. This does not impact any current tests, and may have no direct impact at all because of how that VFS handles locking, but is hypothetically a more correct solution than the previous one.
