hwrng: optee - remove redundant initialization to variable rng_size

Browse Source 
Variable rng_size is being initialized with a value that is never read,
the variable is being re-assigned later on. The initialization is
redundant and can be removed.

Cleans up cppcheck warning:
Variable 'rng_size' is assigned a value that is never used.
