Colin Ian King d9a1aaea85 powerpc/powernv/sriov: perform null check on iov before dereferencing iov 
[ Upstream commit f4f913c980bc6abe0ccfe88fe3909c125afe4a2d ]

Currently pointer iov is being dereferenced before the null check of iov
which can lead to null pointer dereference errors. Fix this by moving the
iov null check before the dereferencing.

Detected using cppcheck static analysis:
linux/arch/powerpc/platforms/powernv/pci-sriov.c:597:12: warning: Either
the condition '!iov' is redundant or there is possible null pointer
dereference: iov. [nullPointerRedundantCheck]
 num_vfs = iov->num_vfs;
           ^
