[PATCH] perf probe: Fix compiles due to declarations using perf_probe_point

[David Ahern]

perf fails to build with gcc "(GCC) 4.4.7 20120313 (Red Hat 4.4.7-4.0.9)"
(a.k.a., RHEL6 / CentOS 6 / OL 6):

cc1: warnings being treated as errors
util/probe-event.c: In function âget_alternative_line_rangeâ:
util/probe-event.c:359: error: missing initializer
util/probe-event.c:359: error: (near initialization for âpp.fileâ)
util/probe-event.c:359: error: missing initializer
util/probe-event.c:359: error: (near initialization for âresult.functionâ)

Fix by bringing in initializers to declaration.
