Roberto Sassu 2e3a34e9f4 ima: Fix return value of ima_write_policy()
This patch fixes the return value of ima_write_policy() when a new policy
is directly passed to IMA and the current policy requires appraisal of the
file containing the policy. Currently, if appraisal is not in ENFORCE mode,
ima_write_policy() returns 0 and leads user space applications to an
endless loop. Fix this issue by denying the operation regardless of the
appraisal mode.

Fixes: 19f8a84713 ("ima: measure and appraise the IMA policy itself")
