`strncpy` is deprecated for use on NUL-terminated destination strings [1].

We know `hw.partname` is supposed to be NUL-terminated by its later use with seq_printf:
| nitrox_debugfs.c +25
|      seq_printf(s, "  Part Name: %s\n", ndev->hw.partname);

Let's prefer a more robust and less ambiguous string interface.

A suitable replacement is `strscpy` [2] due to the fact that it guarantees
NUL-termination on the destination buffer.

Use the request_complete helpers instead of calling the completion
function directly.

xts_check_key() is obsoleted by xts_verify_key(). Over time XTS crypto
drivers adopted the newer xts_verify_key() variant, but xts_check_key()
is still used by a number of drivers. Switch drivers to use the newer
xts_verify_key() and make a couple of cleanups. This allows us to drop
xts_check_key() completely and avoid redundancy.

This driver has been implicitly relying on kmalloc alignment
to be sufficient for DMA.  This may no longer be the case with
upcoming arm64 changes.

This patch changes it to explicitly request DMA alignment from
the Crypto API.

If alloc_workqueue() fails in nitrox_mbox_init() it deallocates
ndev->iov.vfdev and returns error code, but then nitrox_sriov_init()
calls nitrox_sriov_cleanup() where ndev->iov.vfdev is deallocated
again.

Fix this by nulling ndev->iov.vfdev after the first deallocation.
