Error code is not included in the audit messages logged by
the integrity subsystem. Add a new field namely "errno" in
the audit message and set the value to the error code passed
to integrity_audit_msg() in the "result" parameter.

Sample audit message:

[    6.284329] audit: type=1804 audit(1591756723.627:2): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=kernel op=add_boot_aggregate cause=alloc_entry errno=-12 comm="swapper/0" name="boot_aggregate" res=0
