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.
