oprofile: don't request cache line alignment for cpu_buffer
Alignment was previously requested because cpu_buffer was an [NR_CPUS]
array, to avoid cache line sharing between CPUS.
After commit 608dfddd845da5ab6accef70154c8910529699f7 (oprofile: change
cpu_buffer from array to per_cpu variable ), we dont need to force an
alignement anymore since cpu_buffer sits in per_cpu zone.
