nvme-loop: avoid -Wflex-array-member-not-at-end warning

Browse Source 
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

Move the conflicting declaration to the end of the structure. Notice
that `struct nvme_loop_iod` is a flexible structure --a structure
that contains a flexible-array member.

Fix the following warning:

drivers/nvme/target/loop.c:36:33: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
