[Qemu-devel] [PATCH v3 16/18] tests: fix coroutine leak in /basic/entered

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

The coroutine is not finished by the time the test ends, resulting in
ASAN warning:

==7005==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 312 byte(s) in 1 object(s) allocated from:
    #0 0x7fd35290fa38 in __interceptor_calloc (/lib64/libasan.so.4+0xdea38)
    #1 0x7fd3506c5f75 in g_malloc0 ../glib/gmem.c:124
    #2 0x55994af03e47 in qemu_coroutine_new /home/elmarco/src/qemu/util/coroutine-ucontext.c:144
    #3 0x55994aefed99 in qemu_coroutine_create /home/elmarco/src/qemu/util/qemu-coroutine.c:76
    #4 0x55994ac1eb50 in verify_entered_step_1 /home/elmarco/src/qemu/tests/test-coroutine.c:80

    #6 0x7fd34ec02bef  (/lib64/libc.so.6+0x50bef)

Do not yield() to let the coroutine terminate.
