Enable row-mt for deltaq-mode and delta-lf-mode

When row-mt=1, deltaq-mode=1 and/or delta-lf-mode=1,
for the first superblock of every row:

1) xd->current_qindex is reset to base_qindex.
2) loop_filter_delta parameters are reset to default.

This change would avoid the compliance issues arising
due to delta_q_res and delta_lf_res when the above modes
are enabled in encoder.
