getl return LOCK_ERROR for keys which are only on disk and not in memory

set testkey 0 0 5
dummy
STORED

Evict the key from memory using: /opt/membase/bin/ep_engine/management/flushctl localhost:11211 evict testkey

getl testkey
LOCK_ERROR
getl testkey
LOCK_ERROR
gets testkey
VALUE testkey 0 5 6
dummy
END
getl testkey
VALUE testkey 0 5 7
dummy
END

if a get request is made before getl then it works fine.
