  Fix mpt_reset to try mpt_hard_reset more than once, and to try
  mpt_soft_reset more than once. And to wait for MPT_DB_STATE_READY
  twice. I mean, this is crucial- give the IOC a chance to get
  If mpt_reset is called to reinit things, and we succeed, make
  sure to re-enable interrupts. This is what has mostly led to
  system lockup after having to hard reset the chip. Also, if
  we think that interrupts aren't function in mpt_cam_timeout,
  for goodness sake, turn them on again.
  In read_cfg_header, return distinguishing errnos so the caller
  can decide what's an error. It's *not* an error to fail to
  read a RAID page from a non-RAID capable device like the FC929X.
  Some whitespace fixes (removing spaces from ends of lines).
