Subject: [PATCH 0/1] Support ioctl for directories

Steve, all
This patch adds support for using the passthrough ioctl on directories.
To do so, we always create a compound for open/query/close.
Technically, in the case for files when we have a pSMBFile we could just
do the query on the existing handle but that would complicate the code.
If we need to avoid the extra open/close for the file case we could add 
those conditionals if we need to/they cause issues.
