MIPS: perf: Fix build with CONFIG_CPU_BMIPS5000 enabled
commit 1b1f01b653b408ebe58fec78c566d1075d285c64 upstream. arch/mips/kernel/perf_event_mipsxx.c: In function 'mipsxx_pmu_enable_event': arch/mips/kernel/perf_event_mipsxx.c:326:21: error: unused variable 'event' [-Werror=unused-variable] struct perf_event *event = container_of(evt, struct perf_event, hw); ^~~~~ Fix this by making use of IS_ENABLED() to simplify the code and avoid unnecessary ifdefery.
