Ma Ke 3a69dcccd0 pps: add an error check in parport_attach 
[ Upstream commit 62c5a01a57 ]

In parport_attach, the return value of ida_alloc is unchecked, witch leads
to the use of an invalid index value.

To address this issue, index should be checked. When the index value is
abnormal, the device should be freed.

Found by code review, compile tested only.
