    Fix timeout command in ceph-init-wrapper

    When analyzing the ceph-process-states.log file, we observed a
    recurring error scenario. In the /etc/init.d/ceph-init-wrapper
    osd.0 script, the 'timeout' was consistently failing with error
    code 125 on the execute_ceph_cmd function call. This failure was
    due to the absence of a mandatory value parameter, causing
    'timeout' to interpret 'ceph' as an invalid time interval.

    To solve this bug, we introduced the necessary initialization
    of the $WAIT_FOR_CMD variable. This ensures that the command is
    executed correctly, addressing the issue and preventing the
    recurrence of the 'timeout' error."

    Test Plan:
      - PASS: Force the disk process to be reported as hung and
        check the aforementioned log for the desired output.
