9pfs: fix file descriptor leak
The v9fs_create() and v9fs_lcreate() functions are used to create a file
on the backend and to associate it to a fid. The fid shouldn't be already
in-use, otherwise both functions may silently leak a file descriptor or
allocated memory. The current code doesn't check that.
This patch ensures that the fid isn't already associated to anything
before using it.
