Joe Lawrence cf9bd21a41 [SCSI] mpt3sas: fix cleanup on controller resource mapping failure
If mpt3sas_base_map_resources takes an early error path then its
counterpart, mpt3sas_base_free_resources needs to be careful about
cleaning up:

  1 - _base_mask_interrupts and _base_make_ioc_ready require memory
      mapped I/O registers, make sure that this is true.

  2 - _base_free_irq iterates over the adapter's reply_queue_list, so
      move this list head initialization out of _base_enable_msix to
      _scsih_probe so this will always be safe.

  3 - check that the controller PCI device and its BARs have been
      enabled before disabling them.
