gtid/keyring stage: No such file or directory

[Iwo]

I noticed that when SST is not possible due to timeout, an ambiguous message is written in a log file.

2017-09-06T13:14:03.956598Z 0 [Note] WSREP: (7c414c21, 'tcp://0.0.0.0:4567') turning message relay requesting off
WSREP_SST: [ERROR] Possible timeout in receving first data from donor in (20170906 08:15:41.663)
/m/bin/wsrep_sst_xtrabackup-v2: line 971: gtid/keyring stage: No such file or directory
WSREP_SST: [ERROR] Cleanup after exit with status:1 (20170906 08:15:41.666)

It is caused by missing line break in error handling of recv_data_from_donor_to_joiner() in wsrep_sst_xtrabackup-v2 script:

    if [[ ${RC[0]} -eq 124 ]]; then
        wsrep_log_error "******************* FATAL ERROR ********************** "
        wsrep_log_error "Possible timeout in receving first data from donor in "
                        "gtid/keyring stage"
        wsrep_log_error "****************************************************** "
        exit 32
    fi
