As described in the Coccinelle documentation (Documentation/dev-tools/
coccinelle.rst), chain mode should try patch, report, context, and org
modes until one of them succeed.

It turns out that currently, the 'run_cmd_parmap' function, by failing
to run $SPATCH, rather than returning an error code, kills the execution
of the script by executing the exit command, rather than returning the
error code.

This way, when running coccicheck in chain mode, as in:
    $ make coccicheck MODE=chain

the first .cocci file that does not support one of the virtual rules
stops the execution of the makefile, rather than trying the remaining
rules as specified in the documentation.

Therefore, modify the coccicheck script to return the error code,
rather than terminating the script.
