proto: handle split bits covering more than 32 bits
proto_tree_add_split_bits_item_ret_val can handle bits from an arbitrary
sized buffer, as long as it covers no more than 64 bits. If the
octet-aligned mask covers up to 32 bits, then this mask is also shown.
If this mask was larger than 64 bits, then undefined behavior could
occur, so check for that.
For larger masks, instead of "= GmPRS Terminal Type: Unknown (96)",
display "7 bits = GmPRS Terminal Type: Unknown (96)" instead.
