e1000e: fix pci-device enable-counter balance 

This patch removes redundant and unbalanced pci_disable_device() from
__e1000_shutdown(). pci_clear_master() is enough, device can go into
suspended state with elevated enable_cnt.

Bug was introduced in commit 23606cf5d1
("e1000e / PCI / PM: Add basic runtime PM support (rev. 4)") in v2.6.35
