Boris Brezillon 69e14ce883 ubi: fastmap: Fix add_vol() return value test in ubi_attach_fastmap()

commit 40b6e61ac7 upstream.

Commit e96a8a3bb6 ("UBI: Fastmap: Do not add vol if it already
exists") introduced a bug by changing the possible error codes returned
by add_vol():
- this function no longer returns NULL in case of allocation failure
  but return ERR_PTR(-ENOMEM)
- when a duplicate entry in the volume RB tree is found it returns
  ERR_PTR(-EEXIST) instead of ERR_PTR(-EINVAL)

Fix the tests done on add_vol() return val to match this new behavior.
