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.
