The early error exit in p9_stat() returns without zeroing the p9_stat
buffer, resulting in free() being called with an uninitialized pointer.

Fix that by doing the zeroing first.

This is not coherent with the usual conventions: when a function fails,
it is supposed not to have done anything, and thus the caller shouldn't
have to clean anything.

I.e. i'd rather see the free_stat() call be put after the check for
an error returned by p9_stat.

I can do that, but this would require two calls of free_stat() (one in
p9_stat() in an error case reported via req->result, and one in the
caller of p9_stat() in case of no error).
