hwrng: core - Simplify RNG switching from sysfs
If we attempt to use sysfs to change the current RNG in the usual
way i.e. issuing something like:
`echo 8a8a000.rng > /sys/devices/virtual/misc/hw_random/rng_current`
... it will fail because the code doesn't currently take the '\n'
into consideration. Well, now it does.
