Alexander Lobakin d514c8b542 idpf: don't enable NAPI and interrupts prior to allocating Rx buffers 
Currently, idpf enables NAPI and interrupts prior to allocating Rx
buffers.
This may lead to frame loss (there are no buffers to place incoming
frames) and even crashes on quick ifup-ifdown. Interrupts must be
enabled only after all the resources are here and available.
Split interrupt init into two phases: initialization and enabling,
and perform the second only after the queues are fully initialized.
Note that we can't just move interrupt initialization down the init
process, as the queues must have correct a ::q_vector pointer set
and NAPI already added in order to allocate buffers correctly.
Also, during the deinit process, disable HW interrupts first and
only then disable NAPI. Otherwise, there can be a HW event leading
to napi_schedule(), but the NAPI will already be unavailable.

Fixes: d4d5587182 ("idpf: initialize interrupts and enable vport")
