Samasth Norway Ananda 8a84765c62 ima: fix buffer overrun in ima_eventdigest_init_common
commit 923168a0631bc42fffd55087b337b1b6c54dcff5 upstream.

Function ima_eventdigest_init() calls ima_eventdigest_init_common()
with HASH_ALGO__LAST which is then used to access the array
hash_digest_size[] leading to buffer overrun. Have a conditional
statement to handle this.
