[dpdk-stable] [PATCH v2 3/3] eal: fix evaluation of log level option

[David Marchand <david.marchand@redhat.com>]

--log-level option is handled early, no need to reevaluate it later in
EAL init.

Before:
$ echo quit | ./build/app/test/dpdk-test --no-huge -m 512 \
  --log-level=lib.eal:debug \
  --log-level=lib.ethdev:debug --log-level=lib.ethdev:info \
  |& grep -i logtype.level

EAL: lib.eal logtype level changed from info to debug
EAL: lib.ethdev logtype level changed from info to debug
EAL: lib.ethdev logtype level changed from debug to info
EAL: lib.ethdev logtype level changed from info to debug
EAL: lib.ethdev logtype level changed from debug to info

After:
$ echo quit | ./build/app/test/dpdk-test --no-huge -m 512 \
  --log-level=lib.eal:debug \
  --log-level=lib.ethdev:debug --log-level=lib.ethdev:info \
  |& grep -i logtype.level

EAL: lib.eal logtype level changed from info to debug
EAL: lib.ethdev logtype level changed from info to debug
EAL: lib.ethdev logtype level changed from debug to info

Fixes: 6c7216eefd63 ("eal: fix log level of early messages")
Fixes: 1c806ae5c3ac ("eal/windows: support command line options parsing")
