Markus Armbruster 934df91296 qdev: Make qdev_prop_set_drive() match the other helpers 
qdev_prop_set_drive() can fail.  None of the other qdev_prop_set_FOO()
can; they abort on error.

To clean up this inconsistency, rename qdev_prop_set_drive() to
qdev_prop_set_drive_err(), and create a qdev_prop_set_drive() that
aborts on error.

Coccinelle script to update callers:

    @ depends on !(file in "hw/core/qdev-properties-system.c")@
    expression dev, name, value;
    symbol error_abort;
    @@
    -    qdev_prop_set_drive(dev, name, value, &error_abort);
    +    qdev_prop_set_drive(dev, name, value);

    @@
    expression dev, name, value, errp;

    -    qdev_prop_set_drive(dev, name, value, errp);
