ima: Do not free 'entry' before it is initialized

7bc5f447 (ima: define new function ima_alloc_init_template() to
API) moved the initialization of 'entry' in ima_add_boot_aggregate() a
bit more below, after the if (ima_used_chip).

So, 'entry' is not initialized while being inside this if-block. So, we
should not attempt to free it.
