When building with clang (11.0,--buildtype=debug), eal_lcore.c
produces a -Wformat-nonliteral warning from the vfprintf call
in log_early.

Add __rte_format_printf annotation.

Fixes: b8a36b086625 ("eal/windows: improve CPU and NUMA node detection")

v2:
* Use __rte_format_printf instead of disabling the warning
