sfc: don't free_irq()s if they were never requested

Browse source

If efx_nic_init_interrupt fails, or was never run (e.g. due to an earlier
 failure in ef100_net_open), freeing irqs in efx_nic_fini_interrupt is not
 needed and will cause error messages and stack traces.
So instead, only do this if efx_nic_init_interrupt successfully completed,
 as indicated by the new efx->irqs_hooked flag.
