Add missing anomaly workaround for anomaly 05000281 - we can't return to
instructions which cause hardware errors otherwise we trigger the error
again which means we go into an infinite loop of handling, returning, and
retriggering.  This work around confuses gdb when the error occurs as the
PC will seemed to have moved, so a better long term fix will need to be
figured out, but for now this is better than an infinite crash loop.

There are no CONFIG_{BLK,CHR}_DEV_FLASH Kconfig options, and there is no

PIONEER DVD-RW DVRTD08 times out SETXFER if no media is present.  The
device is SATA and simply skipping SETXFER works around the problem.
Implement ATA_HORKAGE_NOSETXFER and apply it to the device.

Reported by Moritz Rigler in the following thread.

  http://thread.gmane.org/gmane.linux.ide/36790

and by Lars in bko#9540.

ata_eh_reset() was missing error return handling after follow-up SRST

This was discovered while testing new WD 2TB drives which take longer

The function jbd2_journal_write_metadata_buffer() calls
jbd_unlock_bh_state(bh_in) too early; this could potentially allow
another thread to call get_write_access on the buffer head, modify the
data, and dirty it, and allowing the wrong data to be written into the
journal.  Fortunately, if we lose this race, the only time this will
actually cause filesystem corruption is if there is a system crash or
other unclean shutdown of the system before the next commit can take
place.
