migration: add error handling to migrate_fd_put_notify(). 

Although migrate_fd_put_buffer() sets MIG_STATE_ERROR if it failed,
since migrate_fd_put_notify() isn't checking error of underlying
QEMUFile, those resources are kept open.  This patch checks it and
calls migrate_fd_error() in case of error.
