afs: Leave cellnum alone for explicit mtpt cell

Browse Source 
When a mountpoint is given an explicit cell, don't alter cellnum.
Cellnum represents the cell for the parent, and is used for
determining whether or not we're crossing a cell boundary.

Previously, this code forced the mount point to always be treated as
foreign (for a mountpoint prefixed with a cell name), or to always be
treated as local (for a mountpoint prefixed with a cell number).
