mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2()
Description

In the Linux kernel, the following vulnerability has been resolved: mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2() As comment of pci_get_device() says, it returns a pci_device with its refcount increased. We need to call pci_dev_put() to decrease the refcount. Save the return value of pci_get_device() and call pci_dev_put() to decrease the refcount.
