roots: drop open_root_nocache log entry

After a few hundred subvol threads start running, the inode cache starts
to thrash, and the log gets spammed with messages of the form:

	"open_root_nocache <subvolid>: <path>"

Ideally there would be some way to schedule work to minimize inode
thrashing.  Until that gets done, just silence the messages for now.
