NFSv4.1: nfs4_proc_layoutreturn must always drop the plh_block_lgets count
Currently it does not do so if the RPC call failed to start. Fix is to move the decrement of plh_block_lgets into nfs4_layoutreturn_release. Also remove a redundant test of task->tk_status in nfs4_layoutreturn_done: if lrp->res.lrs_present is set, then obviously the RPC call succeeded.
