* pager.c (find_address): If !ISREAD, then don't return errors for
access past NP->allocsize, and clear *ADDR and *DISKSIZE. These
can happen through harmless races against truncate.
(pager_write_page): Don't print annoying messages for writes to
unallocated disk. These can happen through harmless races against
truncate, and so we should not pester the console with them.
