um: random: Don't initialise hwrng struct with zero
Initialising the hwrng struct with zeros causes a
compile-time sparse warning:
$ ARCH=um make -j10 W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
...
CHECK arch/um/drivers/random.c
arch/um/drivers/random.c:31:31: sparse: warning: Using plain integer as NULL pointer
Fix the warning by not initialising the hwrng struct
with zeros as it is initialised anyway during module
init.
Fixes: 72d3e093afae ("um: random: Register random as hwrng-core device")
