Bart Van Assche aefed3e554 scsi: qla2xxx: target: Fix offline port handling and host reset handling 
Remove the function qlt_abort_cmd_on_host_reset() because it can do the
following, all of which can cause a kernel crash:

- DMA unmapping while DMA is in progress.
- Call target_execute_cmd() while DMA is in progress.
- Call transport_generic_free_cmd() while the LIO core owns a command.

Instead of trying to abort a command asynchronously, set the 'aborted' flag
and handle the abort after the hardware has passed control back to the
tcm_qla2xxx driver.
