ice: move udp_tunnel_nic and misc IRQ setup into ice_init_pf()

[ 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.
