The hardware-ECC OOB writer delegates to the page writer, which already
issues PAGEPROG, waits for completion and checks the NAND status. The OOB
wrapper then calls nand_prog_page_end_op() again, sending an extra program
confirm without a corresponding program setup. An error on this redundant
operation is returned even though the page writer has already succeeded.

Return the page writer's result directly. This leaves both PIO and DMA
responsible for completing their own program operation and preserves their
error results, including for bad-block-marker writes.
