[char-misc-next] mei: rename struct pci_dev *mei_device to mei_pdev

[char-misc-next] mei: rename struct pci_dev *mei_device to mei_pdev

[Tomas Winkler]

1. rename mei_device variable to mei_pdev to remove
confusion with type 'struct mei_device'
2. mei_pdev no longer need to be gloabal so make it static
 and remove the declaration from the header file
