perf intel-pt: Remove no_force_psb from documentation
no_force_psb was dropped as a late change to the kernel driver. Consequently, remove it from the documentation.

- It stops the driver resetting the byte count to zero whenever

- will produce a PSB anyway.

- In any case, there is still a PSB when the trace is enabled for

- no_force_psb can be used to slightly decrease the trace size but
- may make it harder for the decoder to recover from errors.
