target-i386: Clean up misuse of qdev_init() in realize method

x86_cpu_apic_realize() calls qdev_init() to realize the APIC.
qdev_init()'s error handling has unwanted side effects: it unparents
the device, and it calls qerror_report_err().

qerror_report_err() is always inappropriate in realize methods,
because it doesn't return the Error object.  It either reports the
error to stderr or the human monitor, or it stores it in the QMP
monitor, where it makes the QMP command fail even though the realize
method succeeded.

Fortunately, qdev_init() can't actually fail here, because realize
can't fail for any of the three possible APIC device models.

Clean up by cutting out the qdev_init() middle-man: set property
"realized" directly.
