[for-next][PATCH 4/5] ring-buffer: Remove unnecessary cpumask_test_cpu

[Steven Rostedt <rostedt@kernel.org>]

From: Vincent Donnefort <vdonnefort@google.com>

for_each_buffer_cpu() already iterates over buffer->cpumask. Remove the
unnecessary cpumask_test_cpu() found in ring_buffer_subbuf_order_set().
