[ Upstream commit 2fe18288fce6b421f1dc585bcb9dd3afa32d3ad9 ]
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").
