Subject: [PATCH] scsi: qla2xxx: Remove redundant assignment to rval

Variable rval is set to QLA_SUCCESS, but this value is never read as
it is overwritten later on, hence it is a redundant assignment and
can be removed.

Clean up the following clang-analyzer warning:

drivers/scsi/qla2xxx/qla_init.c:4359:2: warning: Value stored to 'rval'
is never read [clang-analyzer-deadcode.DeadStores].
