ahci: Use pci_enable_msi_exact() instead of pci_enable_msi_range()
The driver calls pci_enable_msi_range() function with the range of [nvec..nvec] which is what pci_enable_msi_exact() function is for. Signed-off-by: Alexander Gordeev <agordeev@redhat.com> Cc: linux-ide@vger.kernel.org Signed-off-by: Tejun Heo <tj@kernel.org>
