[PATCH net-next v4 06/15] gve: introduce ctrl ops to set vectors and Qs

[Harshitha Ramamurthy]

Introduce following ctrl ops for Adminq mode.

- set_num_queues to set maximum and default TX/RX queues in the
  alloc structures used in the initialization flow.
- set_num_ntfy_blks op to set number of vectors(ntfy_blks) in the
  initialization flow.

This is done by attaching the adminq_ prefix to the existing
functions placed in the gve_adminq.c file.

v4: Attach 'adminq_' prefix in the function names for gve_set_num_queues
    and gve_set_num_ntfy_blks and set them as ops (Przemek Kitszel)
