crypto: qat - ignore subsequent state up commands
If the device is already in the up state, a subsequent write of `up` to
the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/state brings the
device down.
Fix this behaviour by ignoring subsequent `up` commands if the device is
already in the up state.
