In 'virResctrlAllocUpdateMask', mask is updated only if 'previous mask' is NULL.
By default, the bitmask for a cache resource for a VM is initialized with 'default-resctrl-group' bitmask. So the 'previous mask' would not be NULL and mask won't get updated if cachetune is configured for a VM. This causes libvirt to use same bitmask as 'default-resctrl-group' bitmask for a cache resource for a VM. This patch fixes the issue.

Thanks for catching this, it seems to be the only such case in that commit.
