Currently in htt_t2h_msg_handler_fast, msg_len, which is in number of
bytes, is directly compared with pdev->rx_mpdu_range_offset_words,
which is in number of words. Thus their comparison becomes invalid.
In htt_t2h_msg_handler, in addition to similar issue as above, the
checks for message offset validations do not consider integer overflows
occurring.
In htt_t2h_msg_handler_fast, the check condition involving
pdev_rx_mpdu_range_offset_words were corrected to work with bytes,
and in htt_t2h_msg_handler checks for integer overflow were also
added.
