msm: kgsl: Remove unnecessary profile close check

Remove an unnecessary profile close check in
adreno_profile_process_results(). The profile close
check was causing NULL pointer dereferencing in
other adreno profile functions. There should be
no danger of memory leak though since we clear the
buffer in adreno_profile_close() anyway.
