[dpdk-dev] [PATCH 2/3] memalloc: fix wrong return value on freeing segment on fail

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

Return value should be zero for success, but if unlock and unlink
have succeeded, return value was 1, which triggered failure message
in calling code.

Fixes: a5ff05d60fc5 ("mem: support unmapping pages at runtime")
