sys: FspFsvolReadNonCached: trim ReadLength
...
During CreateProcess/CreateSection Windows locks the image file (using AcquireFileForNtCreateSection),
gets the image file size and then reads the image file. Unfortunately if the file system (erroneously) reads
past the file size, Windows can bugcheck. This allows a faulty or malicious file system to crash Windows.
This commit adds a check in WinFsp to mitigate this problem.

Fix 32 bit overflow issue in FspFsvolReadCached.
...
FspFsvolReadCached takes care not to read beyond the end of the file.
However, the offset check uses a 32 bit comparison, which fails for
files >= 4G. As a result, reads on a large file will skip blocks at
offset (filesize % 4G), and those blocks will zero-filled.
