generic: convert crypto-ocf from kernel_thread to kthread

recent kernels have finally stopped exporting kernel_thread, since a
deprecation circa 2006.  This patch attempts to convert to the newer
kernel kthread API, particularly in random.c

[juhosg: remove randomproc variable, it is not required after the patch]
