net/bnxt: enable interrupts according interface status

net/bnxt: enable interrupts according interface status

Driver issues hwrm_if_change when the port is started. This command
returns whether the fw has undergone a reset while port was down and
driver does re-init of resources if fw has undergone a reset.
Fix to enable interrupts only after this check.
