rbd showmapped has trailing whitespace which break rbd monitor

Taken from rbd RA

find_rbd_dev() {
    local sedpat

    # Example output from "rbd showmapped" (tab separated):
    # id pool image snap device
    # 0 rbd test - /dev/rbd0

    # Build the sed pattern, substituting "-" for the snapshot name if
    # it's unset
    sedpat="[0-9]\+[ \t]\+${OCF_RESKEY_pool}[ \t]\+${OCF_RESKEY_name}[ \t]\+${OCF_RESKEY_snap:--}[ \t]\+\(/dev/rbd[0-9]\+\)"

    # Run rbd showmapped, filter out the header line, then try to
    # extract the device name
    rbd showmapped | tail -n +2 | sed -n -e "s,$sedpat,\1,p"
}

rbd showmapped is outputing a trailing whitespace character at the end of the block device which means that the monitor check can't find the mapped block device
