BUG/MINOR: tools: Fix a memory leak on error path in parse_dotted_uints()

When an invalid character is found during parsing in parse_dotted_uints()
function, the allocated array of uint must be released. This patch fixes a
memory leak on error path during the configuration parsing.

This patch should fix the issue #1106. It should be backported as far as
2.0. Note that, for 2.1 and 2.0, the function is in src/standard.c
