[dpdk-stable] [PATCH] examples/eventdev_pipeline: fix 32-bit coremask logic

This commit fixes a bug in 32-bit environments when a core mask greater
than 32-bits is requested. The fix is to convert the bitmask logic to
64 bits, aligning 64 and 32 bit implementations.
Fixes: adb5d548 ("examples/eventdev_pipeline_sw_pmd: add sample app")
