[dpdk-dev] [PATCH v2 5/7] eal: bring forward init of interrupt handling

[Anatoly Burakov]

From: Jianfeng Tan <jianfeng.tan at intel.com>

Next commit will make asynchronous IPC requests rely on alarm API,
which in turn relies on interrupts to work. Therefore, move the EAL
interrupt initialization before IPC initialization to avoid breaking
IPC in the next commit.
