IB/fmr_pool: Stop ib_fmr threads from contributing to load average
I noticed my machine was at a constant load average of 1. This was because ib_create_fmr_pool calls kthread_create but does not immediately wake the thread up. Change to using kthread_run so we enter ib_fmr_cleanup_thread(), set TASK_INTERRUPTIBLE, then go to sleep. Signed-off-by: Roland Dreier <rolandd@cisco.com>
