David Howells 7d762d6914 afs: Fix manually set volume location server list 
When a cell with a volume location server list is added manually by
echoing the details into /proc/net/afs/cells, a record is added but the
flag saying it has been looked up isn't set.

This causes the VL server rotation code to wait forever, with the top of
/proc/pid/stack looking like:

	afs_select_vlserver+0x3a6/0x6f3
	afs_vl_lookup_vldb+0x4b/0x92
	afs_create_volume+0x25/0x1b9
	...

with the thread stuck in afs_start_vl_iteration() waiting for
AFS_CELL_FL_NO_LOOKUP_YET to be cleared.

Fix this by clearing AFS_CELL_FL_NO_LOOKUP_YET when setting up a record
if that record's details were supplied manually.
