[dm-devel] [PATCH] multipathd: fail path when path check timeout

[tang.junhui at zte.com.cn]

From: "tang.junhui" <tang.junhui at zte.com.cn>

path should be failed when path status is PATH_TIMEOUT after check,
otherwise, the valid number of paths in the map would be increased when
the path status is PATH_UP after the next turn check, which would cause
the valid number of paths exceeding the total number of paths in the map.
