lvmcache: set device in label when switching devs V2

Browse Source 
This is an alternative/equivalent to commit
ca67cf84df6015c990618de3dc45c0b87eee75ce

The problem (wrong label->dev after a new preferred
duplicate device is chosen) was isolated to the lvmetad
case (non-lvmetad worked fine), and this fixes the problem
by setting the new label->dev in the lvmetad-specific
code rather than in the general lvmcache code.
