tracing: Fix ignored return value of resize_buffer_duplicate_size()
When tr->allocated_snapshot is true, resize_buffer_duplicate_size() is
called to update the snapshot buffer size. However, its return value was
not checked. In case of a failed resize this could lead next snapshot
being incomplete.
Add resize_buffer_duplicate_size() result check and return error if
resize fails.
Compile tested only.
