ixgbe: fix unbalanced device enable/disable in suspend/resume
pci_disable_device() called in __ixgbe_shutdown() decreases
dev->enable_cnt by 1. pci_enable_device_mem() which increases
dev->enable_cnt by 1, was removed from ixgbe_resume() in commit
6f82b2558735 ("ixgbe: use generic power management"). This caused
unbalanced increase/decrease. So add pci_enable_device_mem() back.
Fix the following call trace.
ixgbe 0000:17:00.1: disabling already-disabled device
