UPSTREAM: PCI/ASPM: Restore parent state to parent, child state to child

There's a typo that makes parent device uses child LNKCTL value and vice
versa. This causes Micron NVMe to trigger a reboot upon system resume.

Correct the typo to fix the issue.

Fixes: 64dbb2d7 ("PCI/ASPM: Disable L1 before configuring L1 Substates")
