kiblnd_check_conns() called kiblnd_check_sends() with read_lock(&kiblnd_data.kib_global_lock), it's
so wrong because kiblnd_check_sends() could do a lot of things:
1. lnet_finalize(), which is not safe with spinlock
2. kiblnd_close_conn(), which will hold write_lock(&kiblnd_data.kib_global_lock) to be bomb of
deadlock
There is a patch in the bug from Isaac, but it introduced som regressions and was therefore reverted.
