[PATCH 5.15 215/279] scsi: qla2xxx: Fix mailbox direction flags in qla2xxx_get_adapter_id()

From: Ewan D. Milne <emilne@redhat.com>

commit 392006871bb26166bcfafa56faf49431c2cfaaa8 upstream.

The SCM changes set the flags in mcp->out_mb instead of mcp->in_mb so the
data was not actually being read into the mcp->mb[] array from the adapter.
