lpfc: Fix Device discovery failures during switch reboot test.

BugLink: http://bugs.launchpad.net/bugs/1715430

commit 342b59ca upstream.

When the switch is rebooted, the lpfc driver fails to log
into the fabric, and Unexpected timeout message is seen.

Fix: Do not issue RegVFI if the FLOGI was internally aborted.
