    x86/guest: Fix assembler warnings with newer binutils
    
    GAS of at least version 2.34 complains:
    
      hypercall_page.S: Assembler messages:
      hypercall_page.S:24: Warning: symbol 'HYPERCALL_set_trap_table' already 
has its type set
      ...
      hypercall_page.S:71: Warning: symbol 'HYPERCALL_arch_7' already has its 
type set
    
    which is because the whole page is declared as STT_OBJECT already.  
Rearrange
    .set with respect to .type in DECLARE_HYPERCALL() so STT_FUNC is already in
    place.
