Subject: [PATCH] fix segfault for invalid characters in vg name

Fixes a regression from commit ba7ff96faff0
"improve reading and repairing vg metadata"

where the error path for a vg name with invalid
charaters was missing an error flag, which led
to the caller not recognizing an error occured.
Previously, an error flag was hidden in the old
_vg_make_handle function.
