too many arguments for format string

[peterjc]

Spotted via the compiler warnings trying to build FALCON locally,

src/c/DW_banded.c: In function ‘my_calloc’:
src/c/DW_banded.c:109:17: warning: too many arguments for format [-Wformat-extra-args]
                 msg, nitems, size, lineno);
                 ^

This change expands the logging to record the line number argument.
The message could be logged too, but might be long, so I have included
the ellipse in the message to indicate there is another argument to
calloc not being recorded.

The TravisCI failure looks unrelated?

Should this be submitted as a change against the develop branch? If so, why not make that the default branch on GitHub?

[pb-cdunn]

You're right: develop should be the default branch. But the code in GitHub is no longer kept up-to-date anyway. (We host internally now.)

Thanks for fixing the typo. We'll grab your commit soon ...

[peterjc]

Thanks.
