[ Upstream commit 4a20342572f66c5b20a1ee680f5ac0a13703748f ]

Nothing can stop a host from submitting invalid commands. The target
just needs to respond with an appropriate status, but that's not a
target error. Demote invalid command messages to the debug level so
these events don't spam the kernel logs.
