Huaxin Lu 3b4984035c ima: Fix a potential NULL pointer access in ima_restore_measurement_list 
commit 11220db412 upstream.

In restore_template_fmt, when kstrdup fails, a non-NULL value will still be
returned, which causes a NULL pointer access in template_desc_init_fields.

Fixes: c7d0936770 ("ima: support restoring multiple template formats")
