OvmfPkg/XenBusDxe: fix UninstallMultipleProtocolInterfaces() call 

Unlike the InstallMultipleProtocolInterfaces() boot service, which takes
an (EFI_HANDLE*) as first parameter, the
UninstallMultipleProtocolInterfaces() boot service takes an EFI_HANDLE as
first parameter.

This is an actual bug. It must have remained hidden until now because it's
on an error path. Fix the UninstallMultipleProtocolInterfaces() call.
