Bruce Evans a572c95c3b Don't dump on the label sector or below. This avoids clobbering the 
label if the dump device overflaps the label (which is a slight
misconfiguration).  Dump routines don't use dscheck(), so the normal
write protection of the label doesn't help.

Reduced some nearby overflow bugs.  In disk_dumpcheck(), there was
(fatal but fail-safe) overflow on i386's with 4GB of memory, at least
if Maxmem was the top page (can this happen?).  The fix assumes that
the sector size divides PAGE_SIZE (dump routines already assume this).
In setdumpdev(), the corresponding overflow occurred with only about
2GB of memory on all machines with 32-bit ints.  This allowed setdumpdev()
to succeed when it shouldn't have, but then disk_dumpcheck() failed
safe later.  Except in old versions of FreeBSD like RELENG_3 where
there is no disk_dumpcheck().
