drm/amdgpu: Pack nested ucode_info struct
Building for ARCH=um with W=1 C=1 makes the "amd_sriov_msg_vf2pf_info
must be 1 KB" static assertion in amdgv_sriovmsg.h fail under sparse,
exposed after UML builds were enabled.
Sparse does not honor #pragma pack(push, 1) for the nested ucode_info
struct, so it sizes each element as 8 bytes instead of 5 and computes
the surrounding structure as larger than 1 KB. The compilers get this
right via the enclosing pragma, but the annotation should be explicit.
Fixes: af3f2f5db265 ("drm/amdgpu: Remove UML build exclusion from Kconfig")
