[0.4.13][NTFS] PrintAllVCNs(): Fix a typo in an ASSERT() (#4682), EOL-WS
First part with the typo in the assert was introduced by5579428b4f
which was merged into ros by a merge-task during 0.4.8-dev'ing. releases/0.4.7 didn't have that code yet. fix picked from 0.4.15-dev-5035-gf308c6a2bc
---------- [NTFS] Do not print debug message for every function call by default That 2nd part was picked from 0.4.13-dev-450-g1552434940
This part is not relevant for the backport to releases/0.4.13 and 0.4.14, because it is already inside them. ---------- And for all the files that I had to touch for the 2nd part in the older branches, I ported back also some EOL-whitespace-fixes within like they were done during 0.4.15-dev'ing.
