[PULL 03/16] tests/x86: add helper qtest_qmp_device_del_send()

[Thomas Huth <thuth@redhat.com>]

From: Michael Labiuk <michael.labiuk@virtuozzo.com>

Move sending 'device_del' command to separate function.
Function can be used in case of addition action is needed to start
actual removing device after sending command.
