msm: kgsl: Fix memory leak in kgsl_ioctl_recurring_command()

Currently, profiling flag for recurring command is cleared after
adding a profiling buffer command object. When command object
destroy is called, it won't put refcount for this profiling buffer
as the flag was cleared earlier resulting in a memory leak. Clear
the profiling flag immediately after draw object creation to avoid
refcount on profiling buffer.
