James Cowgill 042b4b169c hwrng: arm-smccc-trng - fix NO_ENTROPY handling ...

The SMCCC_RET_TRNG_NO_ENTROPY switch arm is never used because the
NO_ENTROPY return value is negative and negative values are handled
above the switch by immediately returning.

Fix by handling errors using a default arm in the switch.
