[CIFS] make sure that DFS pathnames are properly formed
The paths in a DFS request are supposed to only have a single preceding
backslash, but we are sending them with a double backslash. This is
exposing a bug in Windows where it also sends a path in the response
that has a double backslash.
The existing code that builds the mount option string however expects a
double backslash prefix in a couple of places when it tries to use the
path returned by build_path_from_dentry. Fix compose_mount_options to
expect properly formed DFS paths (single backslash at front).
Also clean up error handling in that function. There was a possible
NULL pointer dereference and situations where a partially built option
string would be returned.
Tested against Samba 3.0.28-ish server and Samba 3.3 and Win2k8.
