fixup! libmlx5: Extend mlx5dv_get_qp() to return UAR mapping info

Import rdma-core upstream commit d2389b34ccc5 ("mlx5: Add missing include
file in mlx5dv.h").

Including <sys/types.h> keeps mlx5dv.h self-contained: off_t, used by the
new uar_mmap_offset field, is now always defined.  The man page gains the
uar_mmap_offset line upstream documents in 5dd3ead7b5f5.
