[PATCH 4/5] powerpc/powernv: Remove set but not used variable 'pdn'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

arch/powerpc/platforms/powernv/pci-ioda.c: In function pnv_ioda_release_vf_PE:
arch/powerpc/platforms/powernv/pci-ioda.c:1468:25: warning: variable pdn set 
but not used [-Wunused-but-set-variable]

It is introduced by commit 781a868f3136 ("powerpc/powernv:
Shift VF resource with an offset"), but never used, so remove it.
