CVE-2021-47473

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()

Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of
qla2x00_process_els()"), intended to change:

        bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN


        bsg_job->request->msgcode != FC_BSG_RPT_ELS

but changed it to:

        bsg_job->request->msgcode == FC_BSG_RPT_ELS

instead.

Change the == to a != to avoid leaking the fcport structure or freeing
unallocated memory.
