Elena Reshetova 24196f0c7d PCI: hv: Convert hv_pci_dev.refs from atomic_t to refcount_t ...

refcount_t type and corresponding API should be used instead of atomic_t
when the variable is used as a reference counter.  This allows to avoid
accidental refcounter overflows that might lead to use-after-free
situations.
