ibmvnic: Wait until reset is complete to set carrier on

Browse Source 
[ Upstream commit cc85c02edfe48a34865ae00f7d22298a3fdd17aa ]

Pushes back setting the carrier on until the end of the reset
code. This resolves a bug where a watchdog timer was detecting
that a TX queue had stalled before the adapter reset was complete.
