ima: Don't ignore errors from crypto_shash_update()
commit 60386b854008adc951c470067f90a2d85b5d520f upstream.
Errors returned by crypto_shash_update() are not checked in
ima_calc_boot_aggregate_tfm() and thus can be overwritten at the next
iteration of the loop. This patch adds a check after calling
crypto_shash_update() and returns immediately if the result is not zero.
