[LU-11552] improper FMR/FastReg pool cleanup

• Type: Improvement

Description

While porting the map_on_demand changes to the linux lustre client it was noticed that the cleanup for the FMR / FastReg pool handling was wrong. Even when using FMR if the fmr pool is already deleted it will attempt to cleanup the FastReg pool which shouldn't even exist.
