crypto: cavium/nitrox - Replace GFP_ATOMIC with GFP_KERNEL in crypto_alloc_context()
crypto_alloc_context() is only called by nitrox_skcipher_init(), which is
never called in atomic context.
crypto_alloc_context() calls dma_pool_alloc() with GFP_ATOMIC,
which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.
This is found by a static analysis tool named DCNS written by myself.
I also manually check the kernel code before reporting it.
