[PATCH] ubi_create_gluebi: Initialize static volumes with vol->used_bytes

[Jan Altenberg]

Hi all,

I came across a problem which seems to be present since:

commit 941dfb07ed91451b1c58626a0d258dfdf468b593
UBI: set correct gluebi device size

ubi_create_gluebi() leaves mtd->size = 0 for static volumes. So even
existing static volumes are initialized with a size of 0.
See attached patch (applies on top of latest git).
