dll: fuse: fix path arg to release on Create error

Browse Source 
When the kernel sends a `Create` message the WinFsp-FUSE layer creates
and opens the file (as per Windows semantics). Sometimes an additional
operation needs to be performed after the file has been opened, which
may fail. In this case the just opened file must be released.

In this particular case the WinFsp-FUSE layer used to call `release`
with an uninitialized path. This commit fixes the problem.

This problem was originally reported in cgofuse (billziss-gh/cgofuse#58)
