[PATCH 0/1] MR1665: kernelbase: Let GetFileInformationByHandle succeed on unix redirected handle.

[eric pouech (＠epo)]

As these handles to a file don't have an unix-name attached, the
FileAllInformation query fails.
So only implement GetFileInformationByHandle() on top of queries which
don't fail.

I tested if the three ntdll calls instead of one did impact performance.
On cached handles they don't: a simple x100000 loop even shows a
~10% improvement, likely because we don't grab the filename from wineserver.

Note: that NtQueryInformationFile(FileAllInformation) (as other queries
returning file's name) will still fail on these unix-redirected handles.
