Log Message:
Do some error checking in logoutuserdat()

(i.e. user.tab open/lock/read/write failures)

I suspect this function has been failing on Vertrauen under heavy (Guest
login/out) load, but there was no actual error reporting from this function
which opens, locks, read and writes the user.tab file 4 times (!) for every
user logout.

Ideally:
  - this function would return more error details than simply success/failure
  - this function would only open/lock/read/write the user.tab file only once
