[patch 1/1] zfcp: Reorder registration of initial SCSI device

[Christof Schmitt]

[-- Attachment #1: 700-zfcp-reorder-registration.diff --]
[-- Type: text/plain, Size: 1076 bytes --]

From: Christof Schmitt <christof.schmitt@de.ibm.com>

Make sure that the rport registration did complete and then register
SCSI device directly. Otherwise the unit_enqueue would race with the
call to zfcp_scsi_queue_unit_register.
