Kees Cook 1a17e5b513 LoadPin: Ignore the "contents" argument of the LSM hooks 
LoadPin only enforces the read-only origin of kernel file reads. Whether
or not it was a partial read isn't important. Remove the overly
conservative checks so that things like partial firmware reads will
succeed (i.e. reading a firmware header).
