smb/server: fix potential null-ptr-deref of lease_ctx_info in smb2_open()
null-ptr-deref will occur when (req_op_level == SMB2_OPLOCK_LEVEL_LEASE)
and parse_lease_state() return NULL.
Fix this by check if 'lease_ctx_info' is NULL.
Additionally, remove the redundant parentheses in
parse_durable_handle_context().
