Subject: [PATCH] scsi: ufs: bsg: Complete the job on error

When ufs_bsg_request() fails, it returns a non-zero status without calling
bsg_job_done(). bsg_queue_rq() then ends the request with BLK_STS_IOERR
without running bsg_complete(), leaking the job's device reference and
mapped scatterlists.

Always complete the job via bsg_job_done() and return 0, matching other BSG
transports. Requests failing with a negative errno now return it from SG_IO
with the 4-byte result in the reply, while positive status codes still
return 0 from SG_IO with the reply header.
