virsh: improve help text where integers are expected

Browse Source 
* tools/virsh.c (opts_freecell, opts_memtune, opts_vcpupin)
(opts_setvcpus, opts_setmaxmem, opts_setmem)
(opts_migrate_setmaxdowntime): Use VSH_OT_INT when only an integer
is expected.
(vshCmddefHelp, vshCmddefGetData): Allow mandatory VSH_OT_INT
arguments.
