luci-mod-network: typo in wireless.js

[efahl]

This is a trivial one for anyone who is already working on wireless.js:

The non-breaking space character in the badge output has its digits transposed, it's \x0a and it should be \xa0. This causes the badge to be rendered sometimes as two lines, sometimes as three and the jumpy output is pretty annoying. (If you scan the file for \xa0, you'll see the other strings that are properly formatted.)

Here's the line in question:

			value = '---/%d\x0a%s'.format(noiseValue, _('dBm'));
