tracing: Rename tracing_entries_fops to tracing_capacity_fops
Since commit 8a5f63637890 ("ring-buffer: Fix subbuf resize race with ring buffer readers"), "capacity" refers to the memory available for events, while "entries" refers to the number of events in a ring buffer. As a consequence, rename trace_array::entries to capacity to align with this convention. While at it, rename also tracing_total_entries_fops. It is the aggragate of all ring buffer capacities.
