idpf: preserve coalescing settings across resets

Browse source

The IRQ coalescing config currently reside only inside struct
idpf_q_vector. However, all idpf_q_vector structs are de-allocated and
re-allocated during resets. This leads to user-set coalesce configuration
to be lost.

Add new fields to struct idpf_vport_user_config_data to save the user
settings and re-apply them after reset.
