Changpeng Liu 67eb36c7fa nvme: remove aligned attribute 
When testing vfio-user target with QEMU, there is following error log:

ctrlr.c:2143:31: runtime error: member access within misaligned address 0x7fe526a73d98 for type 'struct spdk_nvme_ctrlr_data', which requires 16 byte alignment

For vfio-user transport, the memory buffer is allocated by clients, so
we can't assume the memory is always aligned, just remove the
aligned attribute.
