[PATCH v2 3/6] gdb/infcall: in condition evaluation register target back after infcall.

[Natalia Saiapova <natalia.saiapova@intel.com>]

After an inferior call is finished, the target is unregistered from
the event loop.  However, if the inferior call has happened during
the condition evaluation, we still want to get `stop` events from
other threads in `wait_one`.  So, register the target back.

	* infcall.c (run_inferior_call): In condition evaluation,
	register the target back after the infcall.
