samba - Jun 1999 - 2.0.4b - Bug in dfree > 2GB reporting for 16-bit clients

In 2.0.4b using a 16-bit client (in this case Lanman for DOS), disk space
reporting for partitions greater than 2GB always reports 0 space free.
I've tracked this down to the disk_norm routine in the smbd/dfree.c file.

In the code for adjusting block size and disk size/free values for 16-bit
reporting, WORDMAX was incorrectly being multiplied by 512 before being
compared with bsize. This resulted in the offending values not being
truncated to fit into 16-bit fields.

I've included a patch below to fix this:
