kernel: wipe TLS when dropping to user mode For threads that run in supervisor mode for some time before synchronously dropping to user mode, re-initialize the TLS area to prevent leakage of potentially sensitive information. We did this already for CONFIG_THREAD_USERSPACE_LOCAL_DATA but not the new CONFIG_THREAD_LOCAL_STORAGE. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
