If anyone has any objections, please let me know. ------------------ From: Przemek Kitszel [ Upstream commit e3bf1cdde7471bab7fc20dd1a37c2cdb82d3f76b ] Move udp_tunnel_nic setup and ice_req_irq_msix_misc() call into ice_init_pf(), remove some redundancy in the former while moving. Move ice_free_irq_msix_misc() call into ice_deinit_pf(), to mimic the above in terms of needed cleanup. Guard it via emptiness check, to keep the allowance of half-initialized pf being cleaned up.
