[Qemu-devel] [PATCH 01/10] coroutine: use qemu_coroutine_switch() directly

[Lai Jiangshan]

When qemu_coroutine_switch() in the qemu_coroutine_yield() returns,
It must be someone calls qemu_coroutine_enter() for it, so the @to
is active, the tests in coroutine_swap() are unneeded, so we use
qemu_coroutine_switch() directly in qemu_coroutine_yield().
