Fix incorrect path conversion on non-existent files on network shares
NtOpenFile/NtCreateFile on non-existent paths on network drives has a
bug. Assuming a path Z:\dir\file. Further assuming that Z:\dir does
not exist.
The first NtOpenFile("Z:\dir\file") correctly returns
STATUS_OBJECT_PATH_NOT_FOUND. Subsequent calls incorrectly
return STATUS_OBJECT_NAME_NOT_FOUND.
This appears to be some kind of caching behaviour. Waiting a while
before repeating the call correctly returns STATUS_OBJECT_PATH_NOT_FOUND
again.
This patch works around the observed misbehaviour.
