hwrng: fetch randomness only after device init
Commit d9e7972619334 "hwrng: add randomness to system from rng sources"
added a call to rng_get_data() from the hwrng_register() function.
However, some rng devices need initialization before data can be read
from them.
This commit makes the call to rng_get_data() depend on no init fn
pointer being registered by the device. If an init function is
registered, this call is made after device init.
