This patch corrects target_semid64_ds structure definition for Mips.

See, for example definition of semid64_ds for Mips in Linux kernel:
arch/mips/include/uapi/asm/sembuf.h#L13.

This patch will also fix certain semaphore-related LTP tests for Mips,
if they are executed in Qemu user mode for any Mips platform.
