Patch that fixes the problem

Currently fasttrap_pid_probe() is using a undefined variable, which causes
the kernel build to fail on powerpc when using a newer compiler.

This patch simply derefence ->pc after rp is defined.

This regression was added by commit
b0b9b4fcf4a7a712c3270a5fde519c199b11fc87('Pass the trap frame to fasttrap
hooks.');
