ntfstruncate.c: Fix mixed endianness usage of variable 'i'.

Browse Source 
In 'dump_resident_attr_val', 'i' was sometimes used as a native-endian
'int'-precision string length value and sometimes used as a little-
endian 16-bit flags value. This type of mixed usage is bad practice and
results in a hard error when strict endianness checking is used.

Fixed by introducing new variable 'flags' to hold the little-endian 16-
bit flags value.
