[PATCH v2 7/8] cmd: ubi: allow creating volume with all free spaces in ubi_create_vol

[Weijie Gao]

Although the ubi command itself supports creating volume with all
free spaces, the api ubi_create_vol() does not.

Since negative size is invalid, this patch replaces negative size
with all free space size in ubi_create_vol().
