cfg80211: fix regresion on reg user timeout
The patch "cfg80211: add a timer for invalid user reg hints" introduced a regression for the case where a secondary identical regulatory hint from a user is sent. What would happen is the second hint would schedule delayed work in to catch a timeout but since we are never processing it given that the hint was already applied we'd always hit the timeout and and restore regulatory settings back to world regulatory domain. This is fixed by simply avoiding sheduling work if the hint was already applied. Tested-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Luis R.
