no_force_psb was dropped as a late change to the kernel driver.
Consequently, remove it from the documentation.

-               will produce a PSB anyway.
-
-               In any case, there is still a PSB when the trace is enabled for
-               the first time.
-
-               no_force_psb can be used to slightly decrease the trace size but
-               may make it harder for the decoder to recover from errors.
-
-               no_force_psb is not selected by default.
