ieee1394: ohci1394: proper log messages in suspend and resume

 - correct thinko in one of my last commits: cannot use PRINT macro with
   ohci == NULL
 - add log messages on ohci == NULL and on pci_enable_device != 0
 - update log macros from patch "revert fail on error in suspend" to use
   PRINT and DBGMSG where possible
