wifi: wcn36xx: Slightly optimize PREPARE_HAL_BUF()
In most (likely all) cases, INIT_HAL_MSG() is called before
PREPARE_HAL_BUF().
In such cases calling memset() is useless because:
msg_body.header.len = sizeof(msg_body)
So, instead of writing twice the memory, we just have a sanity check to
make sure that some potential trailing memory is zeroed.
It even gives the opportunity to see that by itself and optimize it away.
