Vincent Donnefort 8b502bf6eb ring-buffer: Remove ring_buffer_per_cpu::mapped ...

ring_buffer_per_cpu::mapped tracks if a ring-buffer is either mapped by
user-space or if it is a persistent buffer. We already have user_mapped
for the former and ring_meta for the latter. Get rid of mapped and
instead create rb_is_static(). A static ring-buffer cannot be resized,
swapped or have its pages extracted.
