Add load-only timer_mim coverage for inner map identities propagated through nested timer and bpf_for_each_map_elem() callbacks. The negative case initializes a timer in the second inner map with the map saved from the first inner map timer callback. The positive case pairs the timer value with the map supplied to the same for-each callback. Without the verifier fix, the mismatched-map program is accepted while the same-map control is rejected. Preserving map_uid reverses both verdicts.
