This patch fixes a build bug triggered by one of the RCU commits
queued for 3.16.
The definition for raw_cpu_add_return() uses the operation prefix
"raw_add_return_", but the definitions in the various percpu.h files
expect "raw_cpu_add_return_". This commit therefore appropriately
adjusts the definition of raw_cpu_add_return().
