[PATCH][next] io_uring: Fix incorrect ordering of assinments of sqe and opcode

[Colin Ian King <coking@nvidia.com>]

Currently opcode is being assigned to a dereferenced pointer sqe before
sqe is being assigned. It appears the order of these two assignments cs
the wrong way around. Fix this by swapping the order of the assignments.

Fixes: 31dc41afdef2 ("io_uring: add support for IORING_SETUP_SQE_MIXED")
