lpfc: Vport creation is failing with "Link

[backport of f0b2223a666e93c84fd42a0c5dad8a17c08aa869]
From: rkennedy <dick.kennedy@avagotech.com>

Orabug: 26439257

Vport creation fails for SLI-3 adapters.

Mailbox submission fails because mailbox interrupt is disabled. Mailbox
interrupt is disabled during port reset.

Do reset only for physical port.
