Subject: [PATCH 2.6.7-mm3] ipr: minor fixes and assorted nit

- balance pci_enable_device() with pci_disable_device() where appropriate;
- pci_release_regions() replaces release_mem_region();
- ipr_alloc_mem() can not simply issue a call to ipr_free_mem() when
  something goes wrong as it would lead to pci_free_consistent() of
  unset data. Let ipr_alloc_mem() carefully release whatever it has
  allocated instead;
- no need to memset(..., 0, ...) an area returned by pci_alloc_consistent;
- ipr_probe_ioa:
  + DMA_32BIT_MASK for all;
  + error path rework (includes bug fix when ipr_alloc_mem fails);
- ipr_init() can fail: return adequate status code.
