wifi: rtw89: use flexible array member in rtw89_btc_btf_tlv
struct rtw89_btc_btf_tlv contains a one-byte member that is intended as a
flexible array:
In function 'fortify_memcpy_chk',
inlined from '_append_tdma' at drivers/net/wireless/realtek/rtw89/coex.c:1579:3:
include/linux/fortify-string.h:583:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
583 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Make this actually use a flexible array to let the compiler understand.
