Revert "ipc/sem.c: optimize sem_lock()"

This reverts commit 901f6fedc5340d66e2ca67c70dfee926cb5a1ea0
(upstream commit 6d07b68ce16ae9535955ba2059dedba5309c3ca1).

As suggested in commit 5864a2fd3088db73d47942370d0f7210a807b9bc
(ipc/sem.c: fix complex_count vs. simple op race) since it introduces
a regression and the candidate fix requires too many changes for 3.10.
