block/mirror: Fix child permissions
We cannot use bdrv_child_try_set_perm() to give up all restrictions on
the child edge, and still have bdrv_mirror_top_child_perm() request
BLK_PERM_WRITE. Fix this by making bdrv_mirror_top_child_perm() return
0/BLK_PERM_ALL when we want to give up all permissions, and replacing
bdrv_child_try_set_perm() by bdrv_child_refresh_perms().
The bdrv_child_try_set_perm() before removing the node with
bdrv_replace_node() is then unnecessary. No permissions have changed
since the previous invocation of bdrv_child_try_set_perm().
