xen/tracing: fix compile errors when tracing is disabled.
When CONFIG_FUNCTION_TRACER is disabled, compilation fails as follows:

arch/x86/xen/trace.c:6: error: array index in initializer not of integer type

Fix this by making sure struct multicall_entry has a declaration in
scope at all times, and don't bother compiling xen/trace.c when tracing
is disabled.
