[Intel-wired-lan] [PATCH iwl-next 3/9] ice: move ice_init_interrupt_scheme() prior ice_init_pf()

[Przemek Kitszel]

Move ice_init_interrupt_scheme() prior ice_init_pf().
To enable the move ice_set_pf_caps() was moved out from ice_init_pf()
to the caller (ice_init_dev()), and placed prior to the irq scheme init.

The move makes deinit order of ice_deinit_dev() and failure-path of
ice_init_pf() match (at least in terms of not calling
ice_clear_interrupt_scheme() and ice_deinit_pf() in opposite ways).

The new order aligns with findings made by Jakub Buchocki in
the commit 24b454bc354a ("ice: Fix ice module unload").
