ice_if_init marks DRIVER_INITIALIZED only after all queue and filter operations succeed, so ice_if_stop intentionally does nothing after an initialization failure. Each failure path must therefore unwind any hardware queues it may have configured before iflib releases their DMA mappings. Tx setup enables firmware scheduler queues one at a time, and Rx enable similarly processes queues incrementally. Route failures from both operations through cleanup paths for both the PF and mirror VSIs. The cleanup helpers tolerate queues which were not configured, so they also cover failures on the first queue. This leaves failed initialization stopped as required by the iflib_init_failed contract.
