Todd Brandt 200421a80f libata: async resume 
Improve overall system resume time by making libata link recovery
actions asynchronous relative to other resume events.

Link resume operations are performed using the scsi_eh thread, so
commands, particularly the sd resume start/stop command, will be held
off until the device exits error handling.  Libata already flushes eh
with ata_port_wait_eh() in the port teardown paths, so there are no
concerns with async operation colliding with the end-of-life of the
ata_port object.  Also, libata-core is already careful to flush
in-flight pm operations before another round of pm starts on the given
ata_port.
