parisc: Fix locking in pdc_iodc_print() firmware call

commit 7236aae5f81f3efbd93d0601e74fc05994bc2580 upstream.

Utilize pdc_lock spinlock to protect parallel modifications of the
iodc_dbuf[] buffer, check length to prevent buffer overflow of
iodc_dbuf[], drop the iodc_retbuf[] buffer and fix some wrong
indentings.
