[PATCH] v9fs: replace strlen on newly allocated by __getname buffers to PATH_MAX

v9fs_vfs_readlink allocates space for the link using __getname and
errorneously uses strlen on the newly allocated buffer to check if the buffer
passed by the user is bigger than the one returned by __getname.

The patch replaces the strlen usage to PATH_MAX, which is the actual size of
the buffers returned by __getname.
