A newer and better verbs based registration/de-registration method called FRWR (Fast Registration Work Request) was added to RDS by commit 1659185fb4d0 ("RDS: IB: Support Fastreg MR (FRMR) memory registration mode") in 2016. Detection and enablement of FRWR was done in commit 2cb2912d6563 ("RDS: IB: add Fastreg MR (FRMR) detection support"). But said commit added an extern bool prefer_frmr, which was not used by said commit - nor used by later commits. Hence, remove it.
