[PATCH] crypto: inside-secure - Fix the return value of safexcel_xcbcmac_cra_init()

[Li Huafei <lihuafei1@huawei.com>]

The commit 320406cb60b6 ("crypto: inside-secure - Replace generic aes
with libaes") replaced crypto_alloc_cipher() with kmalloc(), but did not
modify the handling of the return value. When kmalloc() returns NULL,
PTR_ERR_OR_ZERO(NULL) returns 0, but in fact, the memory allocation has
failed, and -ENOMEM should be returned.
