[PATCH] Cleanup num_found usage in gdb_wait_for_event

[Simon Marchi]

Probably an artifact from the past, managing num_found in those loops is
not need.

Regtested on Ubuntu 14.04 x64, although only with use_poll == 1.

gdb/ChangeLog:

	* event-loop.c (gdb_wait_for_event): Cleanup uneeded usages of
	num_found.
