fix bug: frame data read from network was potentially being moved inside buffer (lb_normalize()) before it was processed by caller to read_frame()

change hton() and ntoh() so we don't use (u8 *) to (u16 *) casts. Some compilers incorrectly change the pointer to force alignment with even addresses.

Variables start_addr and count were read from query_packet using function mb_ntoh_safe. It looks like some compilers change the pointer alignment if the first byte starts at an odd address. Because mb_ntoh_safe uses pointers slave address and count (number of registers) were not read correctly from the buffer when several modbus slaves were present in network. In this temporary solution pointer aritmetics is replaced by simple 256 multiplication.
