NFS: Don't discard pNFS layout segments that are marked for return
stable inclusion from linux-4.19.191 commit d51316b13dd4f35aa737d20822a18c131eed32c3 -------------------------------- commit 39fd01863616964f009599e50ca5c6ea9ebf88d6 upstream. If the pNFS layout segment is marked with the NFS_LSEG_LAYOUTRETURN flag, then the assumption is that it has some reporting requirement to perform through a layoutreturn (e.g. flexfiles layout stats or error information).
