[dpdk-dev] [PATCH] memalloc: fix variable shadowing

[Anatoly Burakov <anatoly.burakov@intel.com>]

A local variable ``flags`` was shadowing another variable from outer
scope. Fix this by renaming the variable and make it const.

Fixes: c127be93f619 ("mem: support using memfd segments for in-memory mode")
