crypto: ccree - Fix use after free in cc_cipher_exit()

In the Linux kernel, the following vulnerability has been resolved:

crypto: ccree - Fix use after free in cc_cipher_exit()

kfree_sensitive(ctx_p->user.key) will free the ctx_p->user.key. But

ctx_p->user.key is still used in the next line, which will lead to a

use after free.

We can call kfree_sensitive() after dev_dbg() to avoid the uaf.
