Subject: mem: fix index for unmapping segments on failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b3b1b83bad2f6258be866a3687c0cf1bf6b0668c;p=dpdk.git

mem: fix index for unmapping segments on failure

Segment index was calculated incorrectly, causing free_seg to
attempt to free segments that do not exist.

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