oprofile: remove nr_available_slots()
This function is no longer available after the port to the new ring buffer. Its removal can lead to incomplete sampling sequences since IBS samples and backtraces are transfered in multiple samples. Due to a full buffer, samples could be lost any time. The userspace daemon has to live with such incomplete sampling sequences as long as the data within one sample is consistent. This will be fixed by changing the internal buffer data there all data of one IBS sample or a backtrace is packed in a single ring buffer entry. This is possible since the new ring buffer supports variable data size. Signed-off-by: Robert Richter <robert.richter@amd.com>
