Chuck Lever 38f1932e60 xprtrdma: Remove FMRs from the unmap list after unmapping ... ib_unmap_fmr() takes a list of FMRs to unmap. However, it does not remove the FMRs from this list as it processes them. Other ib_unmap_fmr() call sites are careful to remove FMRs from the list after ib_unmap_fmr() returns. Since commit 7c7a5390dc ("xprtrdma: Add ro_unmap_sync method for FMR") fmr_op_unmap_sync passes more than one FMR to ib_unmap_fmr(), but it didn't bother to remove the FMRs from that list once the call was complete. I've noticed some instability that could be related to list tangling by the new fmr_op_unmap_sync() logic. In an abundance of caution, add some defensive logic to clean up properly after ib_unmap_fmr().
