s3:smbd/msdfs: pass 'allow_broken_path' to get_referred_path()
Note the DCERPC code should not be smb2 specific!
I wonder why this is at all smb2 specific...

s3:smbd/files: work without sconn->file_bmap and assign fsp->fnum = -1
For faked connection_structs we do not need valid fnum values,
e.g. in the dfs and printing code.
