x86/pci: Rename pci_mmcfg_check_reserved() to pci_mmcfg_reserved()

"pci_mmcfg_check_reserved()" doesn't give a hint about what the boolean
return value means.  Rename it to pci_mmcfg_reserved() so testing
"if (pci_mmcfg_reserved())" makes sense.

Update callers to treat the return value as boolean instead of comparing
with 0.
