Add default initialization of xd->tile_ctx for row-mt=1

When master thread does not pick any encode job for row-mt=1,
xd->tile_ctx contains NULL pointer. This can result in NULL
pointer violation if accessed beyond the encode stage.
Hence, this CL updates xd->tile_ctx with pointer to common frame
context (cm->fc) in enc_row_mt_worker_hook() to avoid such cases.

This patch also reverts following patch, as xd->tile_ctx
is updated appropriately in enc_row_mt_worker_hook().
