Andrzej Hajda 3834966538 perf tools: Fix handling read result using a signed variable 
The function can return negative value, assigning it to unsigned
variable can cause memory corruption.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].
