Subject: [PATCH 0/2] io_uring: Pass whole sqe to commands

These two patches prepares for the sock support in the io_uring cmd, as
described in the following RFC:

	https://lore.kernel.org/lkml/20230406144330.1932798-1-leitao@debian.org/

Since the support described above depends on other refactors, such as the sock
ioctl() sock refactor[1], I would like to start integrating patches that have
consensus and can bring value right now.  This will also reduce the patchset
size later.

Regarding to these two patches, they are simple changes that turn io_uring cmd
subsystem more flexible (by passing the whole SQE to the command), and cleaning up an
unnecessary compile check.

These patches were tested by creating a filesyste and mounting an NVME disk
using ubdsrv/ublkb0.
