Remove misleading comment (b/26948053)
Vold is considered part of our trusted computing base, and
compromising vold is already identified as a complete device
compromise. While storing keys only in the kernel would be better, the
current setup does not introduce a security bug or worsen any security
control.
Bug: 26948053
Test: Comment-only change.
