Since commit 39850ed51062 ("PCI/PTM: Save/restore Precision
Time Measurement Capability for suspend/resume") devices
which have PTM capability but don't enable it see this
message on calls to pci_save_state():
"no suspend buffer for PTM"
Drop the message, it's perfectly fine not to use a capability.
Fixes: 39850ed51062 ("PCI/PTM: Save/restore Precision Time Measurement Capability for suspend/resume")
