struct set_multicast uses (implicitly) sizeof(bool) to determine how many bytes to copy in
Handle_SetMulticastFilter. Since that is implementation defined, it triggered sparse to
rightfully complain about shifting a bigger value than supported.
Since it was used as if assuming it was 32 bits, I replaced the bool member by a u32.
Also, time_out and buf_size members of ba_session_info are u16, but while copying their
bytes into ptr in Handle_AddBASession shift 16 bits for the second byte instead of 8 bits.
This patch fixes those two issues.
