Zhao Li 927ee844c4 wifi: nl80211: clean up color-change beacon data on errors
nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next
template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies.
A parsing failure returned directly instead of using the out: cleanup,
leaking any allocations completed before the error.

Allocate the nested attribute table before parsing beacon_next. Its
allocation failure can then return before beacon data exists, while a
later parsing failure uses out: to release the parsed data.

Fixes: dc1e3cb8da ("nl80211: MBSSID and EMA support in AP mode")
