ima: Directly free *entry in ima_alloc_init_template() if digests is NULL
To support multiple template digests, the static array entry->digest has been replaced with a dynamically allocated array in commit aa724fe1 ("ima: Switch to dynamically allocated buffer for template digests"). The array is allocated in ima_alloc_init_template() and if the returned pointer is NULL, ima_free_template_entry() is called. However, (*entry)->template_desc is not yet initialized while it is used by ima_free_template_entry(). This patch fixes the issue by directly freeing *entry without calling ima_free_template_entry().
