Subject: [PATCH] padata: Remove unused but set variables

Remove the unused but set variable pinst in padata_parallel_worker to
fix the following warning when building with 'W=1':

kernel/padata.c: In function ‘padata_parallel_worker’:
kernel/padata.c:68:26: warning: variable ‘pinst’ set but not used [-Wunused-but-set-variable]

Also remove the now unused variable pd which is only used to set pinst.
