smbd: Prevent creation of vetoed files
The problem is when checking for vetoed names on the last path component in
openat_pathref_fsp_case_insensitive() we return
NT_STATUS_OBJECT_NAME_NOT_FOUND. The in the caller
filename_convert_dirfsp_nosymlink() this is treated as the "file creation case"
causing filename_convert_dirfsp_nosymlink() to return NT_STATUS_OK.
In order to correctly distinguish between the cases
1) file doesn't exist, we may be creating it, return
2) a vetoed a file
we need 2) to return a more specific error to
filename_convert_dirfsp_nosymlink(). I've chosen NT_STATUS_OBJECT_NAME_INVALID
which gets mapped to the appropriate errror NT_STATUS_OBJECT_PATH_NOT_FOUND or
NT_STATUS_OBJECT_NAME_NOT_FOUND depending on which path component was vetoed.

dsdb/tests: Double number of expressions in large_ldap.py ldap_timeout test
By slowing the filter down more this makes the test reliable on the
autobuild host.
This is not a long-term solution, but is a quick tweak that can be done
today to address current issues with getting commits past the host-based
(compared with cloud-based) autobuild.
