[PATCH] ovl: fix verity lazy-load guard broken by fsverity_active() semantic change

["Colin Walters" <walters@verbum.org>]

Commit f77f281b6118 ("fsverity: use a hashtable to find the fsverity_info")
that broke `ovl_ensure_verity_loaded` in the case when the inode was not in core.

The APIs here are in my opinion now confusing, but this patch intentionally
aims for a minimized fix by using `fsverity_get_info()` which ensures
the hash table is loaded.
