hw/openrisc: Avoid using uninitialised variable 'entry'
clang warns that cpu_openrisc_load_kernel() can use 'entry' uninitialized:
hw/openrisc/openrisc_sim.c:69:9: error: variable 'entry' is used uninitialized
whenever '&&' condition is false [-Werror,-Wsometimes-uninitialized]
if (kernel_filename && !qtest_enabled()) {
^~~~~~~~~~~~~~~
hw/openrisc/openrisc_sim.c:91:19: note: uninitialized use occurs here
cpu->env.pc = entry;
^~~~~
Fix this by not attempting to change the CPU's starting PC unless
we actually loaded a kernel.
