Yu Kuai 3601729d3d scsi: sg: Fix checking return value of blk_get_queue() ...

commit 80b6051085 upstream.

Commit fcaa174a9c ("scsi/sg: don't grab scsi host module reference") make
a mess how blk_get_queue() is called, blk_get_queue() returns true on
success while the caller expects it returns 0 on success.

Fix this problem and also add a corresponding error message on failure.
