[PATCH 2/3] sysemu/xen: Remove unreachable xen_ram_alloc() code

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

The xen_ram_alloc() call in softmmu/physmem.c is guarded
by checking for xen_enabled(), which evaluate to 'false'
when XEN is not built in. The compiler elide the function
call, and thus the inlined function is not used. Remove it.
