[PATCH] perf: Use raw_smp_processor_id insted of smp_processor_id

[Roger Quadros]

gets rid of below messages with CONFIG_DEBUG_PREEMPT enabled

[   28.832916] debug_smp_processor_id: 18 callbacks suppressed
[   28.832946] BUG: using smp_processor_id() in preemptible [00000000] code: modprobe/1763
[   28.841491] caller is pwrdm_set_next_pwrst+0x54/0x120

Tested with perf on OMAP4 Panda.
