[PATCH AUTOSEL 4.19 10/25] scsi: qla2xxx: Fix NPIV create erroneous error

[Sasha Levin]

From: Quinn Tran <qutran@xxxxxxxxxxx>

[ Upstream commit a57214443f0f85639a0d9bbb8bd658d82dbf0927 ]

When user creates multiple NPIVs, the switch capabilities field is checked
before a vport is allowed to be created. This field is being toggled if a
switch scan is in progress. This creates erroneous reject of vport create.
