ring-buffer: Simplify functions with __free(kfree) to free allocations
The function rb_allocate_pages() allocates cpu_buffer and on error needs
to free it. It has a single return. Use __free(kfree) and return directly
on errors and have the return use return_ptr(cpu_buffer).
The function alloc_buffer() allocates buffer and on error needs to free
it. It has a single return. Use __free(kfree) and return directly on
errors and have the return use return_ptr(buffer).
The function __rb_map_vma() allocates a temporary array "pages". Have it
use __free() and not worry about freeing it when returning.
