I see the following errors when rung UBI tests on nandsim:

[ 3698.041511] UBI error: __wl_get_peb: no free eraseblocks
[ 3698.041781] UBI error: ubi_wl_get_fm_peb: no free eraseblocks
[ 3714.773064] UBI error: __wl_get_peb: no free eraseblocks
[ 3714.773336] UBI error: ubi_wl_get_fm_peb: no free eraseblocks

How can this happen? I do not have any bad blocks.

If I understand correctly, it can be only because of a bug. If I am
correct, could you please add a 'dump_stack()' to improve the error
report?
