hwrng: exynos - Fix unbalanced PM runtime put on timeout error path
commit f1925d78d7b710a1179828d53e918295f5f5d222 upstream.
In case of timeout during read operation, the exit path lacked PM
runtime put. This could lead to unbalanced runtime PM usage counter thus
leaving the device in an active state.
Fixes: d7fd6075a205 ("hwrng: exynos - Add timeout for waiting on init done")
