[dpdk-stable] [PATCH] eal/windows: vfprintf build warning with clang

[Nick Connolly]

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

Disable the warning for log_early when building with clang.
MinGW does not seem to detect the warning.

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