evm: reset EVM status when file attributes change
The EVM verification status is cached in iint->evm_status and if it
was successful, never re-verified again when IMA passes the 'iint' to
evm_verifyxattr().
When file attributes or extended attributes change, we may wish to
re-verify EVM integrity as well. For example, after setting a digital
signature we may need to re-verify the signature and update the
iint->flags that there is an EVM signature.
This patch enables that by resetting evm_status to INTEGRITY_UKNOWN
state.
Changes in v2:
* Flag setting moved to EVM layer
