qtest: fix infinite loop when QEMU aborts abruptly
From Markus:
Makes "make check" hang:
QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 gtester -k --verbose -m=quick tests/crash-test tests/rtc-test
TEST: tests/crash-test... (pid=972)
qemu-system-x86_64: Device needs media, but drive is empty
[Nothing happens, wait a while, then hit ^C]
make: *** [check-qtest-x86_64] Interrupt
This was due to the fact that we weren't checked for errors when
reading from the QMP socket. This patch adds appropriate error
checking.
