From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
[ Upstream commit 9816ef6ecbc102b9bcbb1d83e12c7fb19924f38c ]
The error message dereferences "rqb_entry" so we need to print it first
and then free the buffer.
Fixes: 6c621a2229b0 ("scsi: lpfc: Separate NVMET RQ buffer posting from IO resources SGL/iocbq/context")
