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

Commit f77f281b61 ("fsverity: use a hashtable to find the
fsverity_info") made fsverity_active() check whether the inode has the
verity flag, rather than whether the inode's fsverity_info is loaded.
This broke ovl_ensure_verity_loaded(), which wants to load the
fsverity_info for any verity inodes that haven't had it loaded yet.

Therefore, to check that the fsverity_info hasn't yet been loaded, use
fsverity_get_info(inode) == NULL instead of !fsverity_active(inode).

Also, since fsverity_get_info() now involves a hash table lookup, put
the more lightweight IS_VERITY() flag check first.
