powerpc/perf: Remove set but not used variable 'target'

Browse Source 
Fix gcc '-Wunused-but-set-variable' warning:

arch/powerpc/perf/imc-pmu.c: In function trace_imc_event_init:
arch/powerpc/perf/imc-pmu.c:1292:22: warning: variable target set but not used [-Wunused-but-set-variable]

It is introduced by commit 012ae24484 ("powerpc/perf:
Trace imc PMU functions"), but never used, so remove it.
