fm10k: make default VID available in initialization

Browse Source 
When the PF establishes a connection with Switch Manager(SM), it receives
a logical port range from SM, and registers certain logical ports from
that range. Then a default VID will be sent back from the SM.

This whole transaction - finishing with the default VID being set -
needs to be completed before dev_init returns. If not, the interrupt
setting will subsequently be changed in dev_start according to the RX
queue number, and that can cause this transaction to fail.
