Yanjiang Jin 4842234f83 hwrng: caam - fix rng_unmap_ctx's DMA_UNMAP size problem 
Fix rng_unmap_ctx's DMA_UNMAP size problem for caam_rng, else system would
report the below calltrace during cleanup caam_rng.
Since rng_create_sh_desc() creates a fixed descriptor of exactly 4
command-lengths now, also update DESC_RNG_LEN to (4 * CAAM_CMD_SZ).

caam_jr ffe301000.jr: DMA-API: device driver frees DMA memory with different size [device address=0x000000007f080010] [map size=16 bytes] [unmap size=40 bytes]
