blktrace: fix unlocked access to init/start-stop/teardown
sg.c calls into the blktrace functions without holding the proper queue
mutex for doing setup, start/stop, or teardown.
Add internal unlocked variants, and export the ones that do the proper
locking.
Fixes: 6da127ad0918 ("blktrace: Add blktrace ioctls to SCSI generic devices")
