#     crypto: af_alg - rewrite NULL pointer check
#     
#     Because of the possible alloc failure of the alloc_page(), it could
#     return NULL pointer.
#     And there is a check below the sg_assign_page().
#     But it will be more logical to move the NULL check before the
#     sg_assign_page().
