tools/rtla: Fix unassigned nr_cpus

Browse source

[ Upstream commit b4275b2301 ]

In recently introduced timerlat_free(),
the variable 'nr_cpus' is not assigned.

Assign it with sysconf(_SC_NPROCESSORS_CONF) as done elsewhere.
Remove the culprit: -Wno-maybe-uninitialized. The rest of the
code is clean.
