ahci: skip ATAPI ports and fast-fail on device abort
A CD-ROM (or any ATAPI device) on a scanned port previously made the
driver spin the full 100M-iteration timeout on IDENTIFY, then log a
scary 'timed out' (QEMU leaves ATAPI aborts pending in PxCI instead of
completing the slot; tfd=0x441 = ABRT).
- skip a port up-front when firmware set PxCMD.ATAPI (bit 24)
- bail out of the completion poll as soon as PxTFD.ERR is set, clear
the error bits and any wedged slot, and report the abort instead of
timing out — the port scan stays fast with a CD attached
