… when STATUS_INFO_LENGTH_MISMATCH is returned
Summary
Description
Added iterative algorithm to double the buffer size till the "ntfs max path len" when the NtQuerySystemInformation does not fill the ImageName.MaximumLength (happens in WOW64 WIN10 processes).
I did basic tests to fix the issue #1980 using the test app with extracted code. I did not do the testing using the modified psutil lib itself. It is up to you @giampaolo. Thx.
