/sbin/mount.smb uses USER variable which is set even when
user option not used (since it is the shell variable for the
current user).  This causes mounting smbfs filesystems
without a user to fail since "root" is put on the command
line to smbmount, instead of no user.  Also, since USER
should be in the form of "-U user", smbmount is being told
to make root the password.

The patch below changes USER to SMBUSER.
