Richard Weinberger f82290afc8 mtd: ubi: Fix worker handling
Fixes a bug found on thuban boards, which were for 2 years in
a long-term test with varying temperatures. They showed
problems in u-boot when attaching the ubi partition:

U-Boot# run flash_self_test
Booting from nand
set A...

UBI: scanning is finished

Reason is, that accidentially the U-Boot implementation
from __schedule_ubi_work() did not check the flag
ubi->thread_enabled and started with wearleveling work,
but ubi did not have setup all structures at this point
and crashes.

Solve this problem by splitting work scheduling and processing.
