[IA64] Slim-down __clear_bit_unlock
- I removed the unnecessary barrier() from __clear_bit_unlock().
ia64_st4_rel_nta() makes sure all the modifications are globally
seen before the bit is seen to be off.
- I made __clear_bit() modeled after __set_bit() and __change_bit().
- I corrected some comments sating that a memory barrier is provided,
yet in reality, it is the acquisition side of the memory barrier only.
- I corrected some comments, e.g. test_and_clear_bit() was peaking
about "bit to set".
