ksmbd: fix lease break and ack state handling
Do not skip valid lease states containing WRITE_CACHING when breaking
level-II/read leases for writes and truncates.
Handle lease break acknowledgments according to the SMB2 rule that the
acknowledged state must be a subset of the server's break target. Apply
the acknowledged state directly and keep the break pending on failed ACKs.
