ima: remove unneeded size_limit argument from ima_eventdigest_init_common()
ima: remove unneeded size_limit argument from ima_eventdigest_init_common()

This patch removes the 'size_limit' argument from
ima_eventdigest_init_common(). Since the 'd' field will never include
the hash algorithm as prefix and the 'd-ng' will always have it, we can
use the hash algorithm to differentiate the two cases in the modified
function (it is equal to HASH_ALGO__LAST in the first case, the opposite
in the second).
