Subject: [PATCH] scsi: bnx2fc: Remove meaningless 'bnx2fc_abts_cleanup()' return value assignment

From: SeongJae Park <sjpark@...zon.de>

Commit 122c81c563b0 ("scsi: bnx2fc: Return failure if io_req is already
in ABTS processing") made 'bnx2fc_eh_abort()' to return 'FAILED'
when 'io_req' is alrady in ABTS processing, regardless of the return
value of 'bnx2fc_abts_cleanup()'.  But, it left the assignment of the
return value of 'bnx2fc_abts_cleanup()' to 'rc', which is meaningless
now.  This commit removes it.

This issue was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.
