rds/ib: use system_wq instead of rds_ib_fmr_wq
With cmwq, there's no reason to use dedicated rds_ib_fmr_wq - it's not
in the memory reclaim path and the maximum number of concurrent work
items is bound by the number of devices. Drop it and use system_wq
instead. This rds_ib_fmr_init/exit() noops. Both removed.
