inconsistent pfn type checking in process_page_data

[Olaf Hering <olaf@xxxxxxxxx>]

Andrew,

with commit 93c2ff78adcadbe0f8bda57eeb30b1414c966324 a new function 
process_page_data was added. While filling the mfns array for 
xenforeignmemory_map, the individual pfn types[] are checked in a different way 
than the checking of the result of the mapping attempt. 

Is there a special reason why the first loop uses the various TAB values, and 
the other loop checks XTAB/BROKEN/XALLOC? The sending side also uses the latter.


Olaf
