commit 0fe0781f29dd8ab618999e6bda33c782ebbdb109 upstream.
SMB2_open_init() expects a pre-initialised lease_key when opening a
file with a lease, so set pfid->lease_key prior to calling it in
open_shroot().
This issue was observed when performing some DFS failover tests and
the lease key was never randomly generated.
