Arnd Bergmann 44494b0d1d wifi: mac80211: allocate backup ieee80211_nan_sched_cfg off stack
The ieee80211_nan_sched_cfg structure is too large to keep on the
per thread stack:

net/mac80211/nan.c:251:5: error: stack frame size (1560) exceeds limit (1536) in 'ieee80211_nan_set_local_sched' [-Werror,-Wframe-larger-than]
  251 | int ieee80211_nan_set_local_sched(struct ieee80211_sub_if_data *sdata,

Allocate this dynamically using kmalloc_obj() to reduce the stack
usage of this function to a manageable 344 bytes for the same
configuration.
