[SCSI] hpsa: fix board status waiting code

After a reset, we should first wait for the board to become "not ready",
and then wait for it to become "ready", instead of immediately
waiting for it to become "ready", and do this waiting *after*
restoring PCI config space registers.  Also, only wait 10 secs
for board to become "not ready" after a reset (it should quickly
become not ready.)
