GUO Zihua c591c48842 integrity: Fix memory leakage in keyring allocation error path 
[ Upstream commit 39419ef7af ]

Key restriction is allocated in integrity_init_keyring(). However, if
keyring allocation failed, it is not freed, causing memory leaks.

Fixes: 2b6aa412ff ("KEYS: Use structure to capture key restriction function and data")
