crypto: qat - handle sysfs-triggered reset callbacks

Browse Source 
A reset requested through /sys/bus/pci/devices/.../reset invokes the
driver reset_prepare() and reset_done() callbacks. The QAT driver does
not implement those callbacks today, so the reset proceeds without
quiescing the device or bringing it back up afterward, which leaves
the device unusable.

Hook reset_prepare() and reset_done() into adf_err_handler so the
common shutdown and recovery flow also runs for reset. Skip device
quiesce if the device is already in a down state.
