FUJITA Tomonori 3f27e3ed11 [SCSI] bsg: fix bsg_mutex hang with device removal ...

We don't need to hold bsg_mutex during bsg_complete_all_commands(). It
leads to a problem that we block bsg_unregister_queue during
bsg_complete_all_commands (untill all the outstanding commands
complete).

Thanks to Pete Wyckoff for finding the bug and testing the patch.
