dm log: fix dm_io_client leak on error paths
commit c7a2bd19b7c1e0bd2c7604c53d2583e91e536948 upstream.
In create_log_context function, dm_io_client_destroy function needs
to be called, when memory allocation of disk_header, sync_bits and
recovering_bits failed, but dm_io_client_destroy is not called.
