9pfs: refactor 'name_idx' -> 'nwalked' in v9fs_walk()
The local variable 'name_idx' is used in two loops in function v9fs_walk().
Let the first loop use its own variable 'nwalked' instead, which we will
use in subsequent patch as the number of (requested) path components
successfully walked by background I/O thread.
