[PATCH 2/3] libtracefs utest: Fix a sometimes uninitialized variable.

[Ian Rogers <irogers@xxxxxxxxxx>]

The warning looks like:

utest/tracefs-utest.c:706:7: error: variable 'fd' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
                if (rstat != -1)
                    ^~~~~~~~~~~
