[PATCH] sparc: perf: Remove redundant perf_pmu_{en|dis}able calls

[David Ahern <david.ahern@oracle.com>]

perf_pmu_disable is called by core perf code before pmu->del and the
enable function is called by core perf code afterwards. No need to
call again within sparc_pmu_del.

Ditto for pmu->add and sparc_pmu_add.
