tracing: Remove unused ret assignment in tracing_set_tracer()

Browse Source 
In tracing_set_tracer(), the assignment 'ret = 0' following the
__tracing_resize_ring_buffer() error check is a dead store. After
this point, all subsequent code paths either return with a constant
value (-EINVAL, 0, -EBUSY) or reassign ret before reading it
(tracing_arm_snapshot_locked, tracer_init).

Remove the unnecessary assignment.

No functional change.
