Subject: Converted enumprinters and enumports cmd functions to use WERROR
 values returned from cli functions.  They are converted to NTSTATUS codes
 using the error map functions.

Do buffer size loop checks by setting offered = 0 and using the return
value of needed in the next call.
(This used to be commit 4efbdda3fcfd1fad2f2b8909d250735382497836)
