acl: acl_add can't insert before last list element, fix
Watch this:
$ upstream-qemu -nodefaults -S -vnc :0,acl,sasl -monitor stdio
QEMU 1.5.50 monitor - type 'help' for more information
(qemu) acl_add vnc.username drei allow
acl: added rule at position 1
(qemu) acl_show vnc.username
policy: deny
1: allow drei
(qemu) acl_add vnc.username zwei allow 1
acl: added rule at position 2
(qemu) acl_show vnc.username
policy: deny
1: allow drei
2: allow zwei
(qemu) acl_add vnc.username eins allow 1
acl: added rule at position 1
(qemu) acl_show vnc.username
policy: deny
1: allow eins
2: allow drei
3: allow zwei
The second acl_add inserts at position 2 instead of 1.
Root cause is an off-by-one in qemu_acl_insert(): when index ==
acl->nentries, it appends instead of inserting before the last list
element.
