[libvirt] [PATCH] qemu: Use 'idx' instead of 'index' for variable name

[John Ferlan]

Apparently for Xen-devel 'index' is a global and causes a build failure,
so just use the shortened 'idx' instead to avoid the conflict.

I did try modify cfg.mk to add a syntax check similar to the ii,jj,kk
checks, but it tripped up over 'index' declarations inside structures.
I'd be happy to add one, but I need some help formatting it... Here's
what I had:

sc_prohibit_int_index:
        @prohibit='\<(int|unsigned) ([^(=]* )*(index)\>(\s|,|;)'    \
        halt='use different name than 'index' for declaration'      \
        $(_sc_search_regexp)
