Subject: scsi: qla2xxx: Fix mailbox direction flags in
 qla2xxx_get_adapter_id()
Patch-mainline: v5.16-rc2
Git-commit: 392006871bb26166bcfafa56faf49431c2cfaaa8
References: git-fixes

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.
