powerpc/kernel: Initialize load_tm on task creation

Browse source

commit 7f22ced437 upstream.

Currently tsk->thread.load_tm is not initialized in the task creation
and can contain garbage on a new task.

This is an undesired behaviour, since it affects the timing to enable
and disable the transactional memory laziness (disabling and enabling
the MSR TM bit, which affects TM reclaim and recheckpoint in the
scheduling process).

Fixes: 5d176f751e ("powerpc: tm: Enable transactional memory (TM) lazily for userspace")
