From: Bart Van Assche <bvanassche@acm.org>

[ Upstream commit e209783d66bca04b5fce4429e59338517ffc1a0b ]

Implementations of the .write_pending() callback functions must guarantee
that an appropriate LIO core callback function will be called immediately or
at a later time. Make sure that this guarantee is met for aborted SCSI
commands.
