[dpdk-dev] [PATCH] common/dpaax: fix i686 compilation issue

Meson build on i686, part of DPDK CI, reports: (example report [1])
    *Meson Failed Build #1:
    OS: UB1604-32
    Target: i686-native-linuxapp-gcc
    ../drivers/common/dpaax/dpaax_iova_table.c:121:3: note: in expansion of
    macro ‘DPAAX_DEBUG’
       DPAAX_DEBUG("Invalid memory node values or count. (size=%lu)",

'statbuf.st_size', part of fstat() is a 'off_t' - which should be printable
as '%lu'. But, only a particularly old compiler reports this (5.4.0).
For now, removing the variable being dumped as part of debug.

 - Another option was to use the PRIu32 macros but, in absence of a proper
   verification environment, I wish to take the safer route. In future, if
   need arises, the field would be added to debug logs.
