If device gone during chip reset, ar->normal_mode_fw.board is not initialized, but ath10k_debug_print_hwfw_info() will try to access its member, which will cause 'kernel NULL pointer' issue. This was found using a faulty device (pci link went down sometimes) in a random insmod/rmmod/other-op test. To fix it, check ar->normal_mode_fw.board before accessing the member.
