Two pre-existing issues found while checking the Sashiko report Miquel
pointed at on the large-OOB series [1]; they are independent of that
fix, so they come separately.

The first has been there since the ->exec_op() conversion: the ECC page
write transfers the spare area out of the controller SRAM but nothing
ever puts chip->oob_poi there, so every written page gets whatever the
previous transfer left behind as its OOB. The second is as old as the
driver: a command that timed out can still complete cmd_done from its
late interrupt, and the next command then returns before the hardware
is done.

Tested on a Colibri VF50 and a Colibri VF61 on top of the large-OOB v2
series: UBIFS write/read-back intact, clean ECC counters.
