BUG FIX: LOCKING_SLOW.C in SAMBA 2.0.6

[John E. Malmberg]

In debugging I found this problem.  It does not seem to appear in normal
operation as it can only occur with a corrupt file.

************ Fixed *********
File PROJECT_ROOT:[SAMBA_VMS.LOCKING]LOCKING_SLOW.C;8
 1069     if(read_share_file( 0, fd, lname, &buf, &new_file) != 0) {
 1070       close(fd);

****** Bad Original **************
File CMS_ROOT:[SAMBA.SOURCE.LOCKING]LOCKING_SLOW.C;7
 1069     if(read_share_file( 0, fd, lname, &buf, &new_file)) {
 1070       close(fd);
************

The platform specifics:

Samba Version: 2.0.6
O/S: OpenVMS 7.2
Compiler: DEC C 6.0
