[IA64] Fix spinaphore down_spin()
Typo in down_spin() meant it only read the low 32 bits of the
"serve" value, instead of the full 64 bits. This results in the
system hanging when the values in ticket/serve get larger than
32-bits. A big enough system running the right test can hit this
in a just a few hours.
Broken since 883a3acf5b0d4782ac35981227a0d094e8b44850
