Subject: [PATCH][next] scsi: bnx2fc: remove redundant assignment to variable i

The variable i is being assigned a value that is never read, the
following code path via the label ofld_err never refers to the
variable. The assignment is redundant and can be removed.

Cleans up clang scan warning:
drivers/scsi/bnx2fc/bnx2fc_tgt.c:132:5: warning: Value stored to 'i'
is never read [deadcode.DeadStores]

Applied to 6.10/scsi-staging, thanks!
