wifi-scripts: ucode: fix null dereference for 6GHz-only radios

Browse Source 
he_phy_cap and he_mac_cap in phy_capabilities are only populated inside
the iftype_data loop. On 6GHz-only radios (e.g. QCN9074/ath11k_pci),
when capability bytes are unavailable they remain null, causing null
dereferences in device_htmode_append():

  Reference error: left-hand side expression is null
  if (!(he_phy_cap[3] & 0x80))

Initialise both to [] before the loop and guard the consumer side with
?? [] so bitwise checks conservatively disable beamformer/beamformee/twt
features rather than crashing.
