platform/x86: think-lmi: mutex protection around multiple WMI calls

Browse source

[ Upstream commit c41e0121a1 ]

When an attribute is being changed if the Admin account is enabled, or if
a password is being updated then multiple WMI calls are needed.
Add mutex protection to ensure no race conditions are introduced.
