Subject: [PATCH 1/2] evm: Fix build warnings

From: Roberto Sassu <roberto.sassu@...wei.com>

Fix build warnings (function parameters description) for
evm_read_protected_xattrs(), evm_set_key() and evm_verifyxattr().

Fixes: 7626676320f3 ("evm: provide a function to set the EVM key from the kernel")
Fixes: 8314b6732ae4 ("ima: Define new template fields xattrnames, xattrlengths and xattrvalues")
Fixes: 2960e6cb5f7c ("evm: additional parameter to pass integrity cache entry 'iint'")
