Stripe_readdirp: Fix race in wind/unwind which led to crash

Scenario - The race window exists when before we wind to a stat call
in readdirp_cbk, whereas stats have returned to cbk. We would free up
local, which leads to a crash.

Fix - We assume all entries to be regular files, and set the wind_count
as a multiple of entries * subvol (stat calls). When we encounter a non
regular file, we decrement the windcount accordingly (subvol times). If
the last entry happens to be a non-regular file, and all stat calls have
wound back, we unwind from here itself.
