The recent "fe6c67f ARM: 5901/2: arm/oprofile: reserve the PMU when
starting" commit broke OProfile support on ARM11 MPCore targets by
adding a misplaced "} else {" clause in function em_start() which
results in a call to release_pmu() even though the PMU is in use
which in turn results in an oops while using OProfile. Removing
the stray else clause fixes the problem.
