wifi: brcmfmac: Use struct_size() in code ralated to struct brcmf_dload_data_le
Prefer struct_size() over open-coded versions of idiom:
sizeof(struct-with-flex-array) + sizeof(typeof-flex-array-elements) * count
where count is the max number of items the flexible array is supposed to
contain.
In this particular case, in the open-coded version sizeof(typeof-flex-array-elements)
is implicit in _count_ because the type of the flex array data is u8:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h:941:
941 struct brcmf_dload_data_le {
942 __le16 flag;
943 __le16 dload_type;
944 __le32 len;
945 __le32 crc;
946 u8 data[];
947 };
