Fix null reference errors in device_htmode_append() that prevent 6GHz-only PCIe radios (QCN9074/ath11k_pci) from initializing. he_phy_cap and he_mac_cap remain null when capability bytes are unavailable, causing null dereferences: Reference error: left-hand side expression is null if (!(he_phy_cap[3] & 0x80)) Fix: guard with ?? [] so bitwise checks conservatively disable beamformer features rather than crashing. Fixes openwrt#23488 Signed-off-by: dastarothx <darkastalier@gmail.com>

Fix three null reference errors in device_capabilities() and
device_htmode_append() that prevent 6GHz-only PCIe radios (QCN9074)
from initializing on devices like the Linksys MX8500.
Tested on: Linksys MX8500 (qualcommax/ipq807x), OpenWrt 25.12.4,
QCN9074 6GHz radio, HE160 @ channel 33 (6115 MHz).
