Commit 2f845882ecd2 ("integrity: Add errno field in audit message")
introduced an audit log function that can take an error code. It is
wrapped by integrity_audit_msg() that implicitly sets the error code
argument to zero. The problem is that there are uses of integrity_audit_msg()
such as ima_collect_measurement() that hide the failure cause for
the message.
This series aims to clarify error reasons for failures, and then expose
error codes based on the following criteria:
1. The log depends on a result from earlier callee, and/or
2. The caller function itself returns with that result
ima_release_policy() is the only caller I thought made sense to keep as
is. The message doesn't correlate with a return code, nor does it
depend on a result from an earlier callee in the function.

Changes in v3:
- Condense series to two commits.
- Reduce review churn by adding error code to integrity_audit_msg().
- ima_write_policy() to report -EINVAL instead of result.
- Link to v2: https://lore.kernel.org/r/20260727-report-hash-error-v2-0-30e394f524fc@cloudflare.com
Changes in v2:
- Changes from v1 are now reflected in patch 3.
- Replace all instances of integrity_audit_msg().
- Convert to patch series.
- Link to v1: https://lore.kernel.org/r/20260716-report-hash-error-v1-1-ac19281112e4@cloudflare.com

integrity_audit_msg() hides error codes by wrapping
integrity_audit_message() which obfuscates the underlying reason for the
failure.
Update integrity_audit_msg() call sites to take an error code and report
errors the same as integrity_audit_message().

integrity_audit_msg() wraps integrity_audit_message(). Replace remaining
call sites with the truncated function name. Then remove it since there
are no more callers.
