virtio: vdpa: Fix reference count leak in octep_sriov_enable()

commit b41ca62c0019de1321d75f2b2f274a28784a41ed upstream.

pci_get_device() will increase the reference count for the returned
pci_dev, and also decrease the reference count for the input parameter
from if it is not NULL.

If we break the loop in  with 'vf_pdev' not NULL. We
need to call pci_dev_put() to decrease the reference count.

Found via static anlaysis and this is similar to commit c508eb042d97
("perf/x86/intel/uncore: Fix reference count leak in sad_cfg_iio_topology()")
