[PATCH] v9fs: fix fid management in v9fs_create

Browse source 
v9fs_create doesn't manage correctly the fids when it is called to create a
directory..  The fid created by the create 9P call (newfid) and the one
created by walking to already created file (wfidno) are not used
consistently.

This patch cleans up the usage of newfid and wfidno.
