qerror: Eliminate QERR_DEVICE_NOT_FOUND

Error classes other than ERROR_CLASS_GENERIC_ERROR should not be used
in new code.  Hiding them in QERR_ macros makes new uses hard to spot.
Fortunately, there's just one such macro left.  Eliminate it with this
coccinelle semantic patch:

    @@
    expression EP, E;
    @@
    -error_set(EP, QERR_DEVICE_NOT_FOUND, E)
    +error_set(EP, ERROR_CLASS_DEVICE_NOT_FOUND, "Device '%s' not found", E)
