PCI: hv: Remove unused hv_set_msi_entry_from_desc()

Fix the following build error:

  drivers/pci/controller/pci-hyperv.c:769:13: error: ‘hv_set_msi_entry_from_desc’ defined but not used [-Werror=unused-function]
    769 | static void hv_set_msi_entry_from_desc(union hv_msi_entry *msi_entry,

The arm64 implementation of hv_set_msi_entry_from_desc() is not used after
d06957d7a692 ("PCI: hv: Avoid the retarget interrupt hypercall in
irq_unmask() on ARM64"), so remove it.

Fixes: d06957d7a692 ("PCI: hv: Avoid the retarget interrupt hypercall in irq_unmask() on ARM64")
