[PATCH rdma-next] RDMA/rw: Remove force_mr module parameter

[Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>]

The force_mr module parameter wasn't exposed to the users
from the beginning with the commit a060b5629ab0 ("IB/core: generic RDMA READ/WRITE API").

Because this variable is for very rare debug while doing bringup of new
ULP and/or converting old ULP to new R/W api. There is no need to expose
that parameter to regular users.
