Check if we lost any important data and send a truncation error/warning
SYNOPSIS
Field_longstr::report_if_important_data()
ptr - Truncated rest of string
end - End of truncated string
RETURN VALUES
0 - None was truncated (or we don't count cut fields)
2 - Some bytes was truncated
NOTE
Check if we lost any important data (anything in a binary string,
or any non-space in others). If only trailing spaces was lost,
send a truncation note, otherwise send a truncation error.
