[PATCH 1/4] common/dpaax: fix unused variable warning in non-debug build

[Stephen Hemminger <stephen@networkplumber.org>]

Fix compiler warning on clang-23.

  dpaa_of.c:14:12: warning: variable 'alive' set but not used
        [-Wunused-but-set-global]

The 'alive' flag is only read by DPAAX_HWWARN, which expands to an empty
statement and discards its condition unless RTE_LIBRTE_DPAAX_DEBUG is
defined. Make the empty expansion consume its argument so the condition
is still checked in a non-debug build.

Fixes: 8c83f28cc8a4 ("common/dpaax: move OF library from DPAA bus")
Cc: stable@dpdk.org
