fsck: make sure we don't read an unitialized variable

This use on %n was completely unnecessary: fprintf returns the number of
characters written. And the issue was that if fprintf failed for whatever
reason, it would not process the %n and m would be unitialized. Rework the
code a bit to simplify it.

Coverity CID#1444708.
