[PATCH] nvme: fix another 32-bit build warning

[Arnd Bergmann]

The nvme_user_cmd function was recently moved around from one file
to another, which made a warning reappear that I had fixed before
at some point:

drivers/nvme/host/core.c: In function 'nvme_user_cmd':
drivers/nvme/host/core.c:424:4: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

This applies the same workaround that we have elsewhere in the
driver with an extra type cast to uintptr_t.

Fixes: 1673f1f08c88 ("nvme: move block_device_operations and ns/ctrl freeing to common code")
