crypto: picoxcell - Fix potential race condition bug

[ Upstream commit 64f4a62e3b17f1e473f971127c2924cae42afc82 ]

engine->stat_irq_thresh was initialized after device_create_file() in
the probe function, the initialization may race with call to
spacc_stat_irq_thresh_store() which updates engine->stat_irq_thresh,
therefore initialize it before creating the file in probe function.
