Subject: [PATCH 1/2] perfcounters: fix powerpc build

Commit 4af4998b ("perf_counter: rework context time") changed struct
perf_counter_context to have a 'time' field instead of a 'time_now'
field, but neglected to fix the place in the powerpc perf_counter.c
where the time_now field was accessed. This fixes it.
