MDEV-26830: Wrong ROW_NUMBER in diagnostics upon INSERT IGNORE with

Browse Source 
CHECK violation

Analysis: When there is constraint fail we return non-zero value for
view_check_option(). So we continue the loop which doesn't increment the
counter because it increments at the end of the loop.
Fix: Increment m_current_row_for_warning() at the beginning of loop. This
will also fix similar bugs if any, about counter not incrementing
correctly because of continue.
