kthread: fix return value of kthread_create() upon SIGKILL.

Browse source

commit 8fe6929cfd upstream.

Commit 786235eeba ("kthread: make kthread_create() killable") meant
for allowing kthread_create() to abort as soon as killed by the
OOM-killer.  But returning -ENOMEM is wrong if killed by SIGKILL from
userspace.  Change kthread_create() to return -EINTR upon SIGKILL.
