Using uninitialized variable

[wmaciel]

cppcheck output:

[src/process_iterator_linux.c:41]: (error) Uninitialized variable: uptime

Since the variable uptime is not initialized in line 26, there is a way to reach line 41 and use it's value without ever initializing it.

This appears to have been fixed; would someone who has the right permissions mind closing this issue?
