    xen/gunzip: Fix build with clang after 33bc2a8495f7
    
    The compilation will fail when building Xen with clang and
    CONFIG_DEBUG=y:
    
    make[4]: Leaving directory '/oss/xen/xen/common/libelf'
      INIT_O  gunzip.init.o
    Error: size of gunzip.o:.text is 0x00000019
    
    This is because the function init_allocator() will not be inlined
    and is not part of the init section.
    
    Fix it by marking init_allocator() with INIT.
    
    Fixes: 33bc2a8495f7 ("xen/gunzip: Allow perform_gunzip() to be called 
multiple times")
