rtc: Fix stale data access of seg_map

When segmentation is disabled for a frame, 'cur_frame->seg_map'
was accessed in av1_cyclic_reset_segment_skip() without
initialization. Hence, when segmentation is disabled, do not
call the function av1_cyclic_reset_segment_skip().

Also, when 'cyclic_refresh->skip_over4x4' is set in rt speed
10, 'cur_frame->seg_map' is updated every other 4x4 block.
But the function av1_get_spatial_seg_pred() assumed
'cur_frame->seg_map' to be set for every 4x4 block. Hence,
modify the function av1_get_spatial_seg_pred() to access
data at 8x8 block when 'cyclic_refresh->skip_over4x4' is set.
