When multiple error flags are set, snprintf_error_data created a comma
seperated textual presentation of it. Commit ef853f5553 ("added return value
check of snprintf to prevent possible buffer overflows detected by CodeQL")
removed the increment of count, so the delimiter is no longer added. Fix this
by incrementing count again.
