[PATCH]_stp_free_percpu function definition responding to _stp_alloc_percpu

[bibo,mao]

Hi,
   On the newest 2.6.19-rc2 smp machines, stap fails to run. It
is because _stp_free_percpu is defined as free_percpu macro and
one function at the same time. This patch modifies this, and
replaces for_each_cpu with for_each_possible_cpu macro.

thanks
bibo,mao
