vlen is out of range. All the other failure cases in function
asn1_oid_decode set *oid to NULL on an error, so fix the issue by
ensuring the vlen out of range error also nullifies the pointer.

When running generic/591 after smb2 leases is enable, all smb2 lease ack
requests failed in ksmbd. because cifs client seems to support only smb2
v2 lease. So cifs doesn't update lease state in ack request if epoch is
not set in smb2 lease break request from ksmbd. epoch is used for smb2
v2 leases. So this patch add smb2 create v2 lease context and set
increased epoch in smb2 lease break response.
