qemu_firmware: Accept int in qemuFirmwareOSInterfaceTypeFromOsDefFirmware()

The point of this function is to translate virDomainOsDefFirmware
enum to qemuFirmwareOSInterface enum. However, with my commit
v5.10.0-507-g8e1804f9 we are passing a variable type of
virDomainLoader enum. Make the function accept both enums and
make the enum members correspond to each other.

This fixes clang build.
