Enforced stat/dir_read of a dir results in size=0

Browse Source 
The size field in lfs_info doesn't really make sense for stat/dir_read
when the file is a directory. Still, we should probably set it to 0 os
it's not uninitialized.

Fortunately we were already setting size=0 in _most_ cases, this commit
is mostly just checking for size=0 in more test cases.
