BUG FIX Tale 2 - : LOCKING_SLOW.C in SAMBA 2.0.6

[John E. Malmberg]

Continuing on attempting to get the SHARE_MODES running.

Now this problem occurs when a share file is being created, and still has a
size of 0, when read_share_file() is called.  read_share_file() returns a
zero, but "buf" is returned as NULL.

This causes an Access Violation to occur after old line 1070.

This should be a platform independent issue.

Now SMBSTATUS is reporting accurately the status of the share files for
OpenVMS.

However I am still chasing down share mode locking problems with the SMBD
:-(
