gluster: Fix the recursive goto outs in the source code.

Added a script check_goto.pl, that when run from
the source code root, will scan all .c files to match
the following pattern:

label:
        if (condition)
            goto label;

On finding such a pattern the script will print the file name
and the line number. There are certain cases where the above
recursive pattern is intended. Hence adding those labels to
ignore-labels. Thanks Vijaikumar Mallikarjuna for the perl
script.

Also fixed all such existing errors
