Pierrick Bouvier c044440a42 plugins: fix qemu_plugin_reset
34e5e1 refactored the plugin context initialization. After this change,
tcg_ctx->plugin_insn is not reset inconditionnally anymore, but only if
one plugin at least is active.

When uninstalling the last plugin active, we stopped reinitializing
tcg_ctx->plugin_insn, which leads to memory callbacks being emitted.
This results in an error as they don't appear in a plugin op sequence as
expected.

The correct fix is to make sure we reset plugin translation variables
after current block translation ends. This way, we can catch any
potential misuse of those after a given block, in more than fixing the
current bug.
