afs: Fix directory inode initialisation order

afs: Fix directory inode initialisation order

Fix afs_inode_init_from_status() to call afs_set_netfs_context() before the
switch to do file type-specific initialisation because local directory
changes don't get uploaded to the server, only stored in the cache.

This requires that the file size be set before, so move that up too.

Without this, NETFS_ICTX_SINGLE_NO_UPLOAD as set on directories gets
clobbered.
