Reset _vgs_locked in lvmcache_init()

Browse Source 
Upon successful fork(), _become_daemon() must assert that the locks that
are currently held belong to the parent, not the child.  All of the
child's internal state saying 'this process holds a lock' has to be
reset.

A proper lvmcache_locking_reset() should follow later.
