Guangshuo Li f0cab88ff8 crypto: caam - Add check for kcalloc() in test_len() 
commit 7cf6e0b69b upstream.

As kcalloc() may fail, check its return value to avoid a NULL pointer
dereference when passing the buffer to rng->read(). On allocation
failure, log the error and return since test_len() returns void.

Fixes: 2be0d806e2 ("crypto: caam - add a test for the RNG")
