qom: Use returned bool to check for failure, Coccinelle part
The previous commit enables conversion of
foo(..., &err);
if (err) {
...
}
to
if (!foo(..., errp)) {
...
}
for QOM functions that now return true / false on success / error.
Coccinelle script:

Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Convert manually.
Line breaks tidied up manually.
