mt7921_change_chanctx() configures the channel for monitor vifs but
does not re-assert sniffer mode. mt7925_change_chanctx() does. Match
mt7925 by adding the missing mt7921_mcu_set_sniffer(true) call,
completing the architectural pattern from commit 914189af23b8 ("wifi:
mt76: mt7921: fix channel switch fail in monitor mode").
The user-visible regression this asymmetry produced on v6.17 and v6.18
was addressed by commit cdb2941a516c ("Revert "wifi: mt76: mt792x:
improve monitor interface handling"") in v6.19 and backported to the
6.17.y and 6.18.y stable trees. This patch is defense in depth in
case the NO_VIRTUAL_MONITOR change is reintroduced in a future series.
