hwrng: stm32 - rework error handling in stm32_rng_read()
Try to conceal seed errors when possible. If, despite the error
concealing tries, a seed error is still present, then return an error.
A clock error does not compromise the hardware block and data can
still be read from RNG_DR. Just warn that the RNG clock is too slow
and clear RNG_SR.
