The NCR5380 drivers have a home-spun linked list implementation for

the standard list_head data structure and list operations instead. Remove
the eh_abort_handler rather than convert it. Doing the conversion would
only be churn because the existing EH handlers don't work and get replaced
in a subsequent patch.

Changed since v2:
- Fix NULL pointer dereference in NCR5380_reselect() when SUPPORT_TAGS is
enabled in the atari_NCR5380.c core driver.

Well, using ->host_scribble allows for an easy check on the midlayer if a command has been properly released by the LLDD. But that's just a side-note.
