ahci: Ensure "MSI Revert to Single Message" mode is not enforced
ahci: Use pci_enable_msi_exact
The driver calls pci_enable_msi_range() function with the
range of [nvec..nvec] which what pci_enable_msi_exact()
function is for.

Function pci_enable_msix() should not be called in case
it threw a negative errno from a previous call.
