[PATCH 29/42] lpfc: Fix upcall to bsg done in non-success cases

[James Smart <jsmart2021@gmail.com>]

The scsi transport fc bsg interface does not expect the
bsg_job_done() callback to be done if the bsg request call
returns failure. Several of the HST_VENDOR cases in the driver
unconditionally call bsg_job_done() regardless of the returning
value.

Fix the code to only call bsg_job_done() if the call to
lpfc_bsg_request() will return success.
