dm crypt: fix GFP flags passed to skcipher_request_alloc()
GFP_KERNEL is not supposed to be or'd with GFP_NOFS (the result is
equivalent to GFP_KERNEL). Also, we use GFP_NOIO instead of GFP_NOFS
because we don't want any I/O being submitted in the direct reclaim
path.
Fixes: 39d13a1ac41d ("dm crypt: reuse eboiv skcipher for IV generation")
