ide-tape: always log debug info in idetape_pc_intr() if debugging is enabled
Add DBG_PC_INTR debug level and use it to always log debug info
in idetape_pc_intr() if debugging is enabled.
While at it:
* Use drive->name instead of tape->name.
* Log device name with "DMA finished" message.
This is a preparation for adding generic ide_pc_intr() helper.
