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.
Fixes: 0888d04b47a1 ("hwrng: Add Arm SMCCC TRNG based driver")
