ide: task_end_request() fix
task_end_request() modified to always call ide_end_drive_cmd()
for taskfile requests. Previously, ide_end_drive_cmd() was
called only when IDE_TFLAG_FLAGGED was set. Also,
ide_dma_intr() is modified to use task_end_request().
Enables TASKFILE ioctls to get valid register outputs on
successful completion.
Bart:
- ported it over recent IDE changes
