locktorture: Warn on individual lock_torture_init() error conditions
When running locktorture as a module, any lock_torture_init() issues will be reflected in the error code from modprobe or insmod, as the case may be. However, these error codes are not available when running locktorture built-in, for example, when using the kvm.sh script. This commit therefore adds WARN_ON_ONCE() to allow distinguishing lock_torture_init() errors when running locktorture built-in. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
