video: driver: sort input timestamp for ts_reorder case

For timestamp reorder feature, input ts is propagated to
output as it is. This is to ensure if app queues linear
order ts for bframe enabled case, it will make sure to
avoid jumbled output ts(due to DPB reordering). But looks
like client requirement is to always get sorted output
timestamp. So added change to produce output ts always
in sorted order.
