NFS: blocklayout pipe creation per network namespace context introduced
This patch implements blocklayout pipe creation and registration per each existent network namespace. This was achived by registering NFS per-net operations, responsible for blocklayout pipe allocation/register and unregister/destruction instead of initialization and destruction of static "bl_device_pipe" pipe (this one was removed). Note, than pointer to network blocklayout pipe is stored in per-net "nfs_net" structure, because allocating of one more per-net structure for blocklayout module looks redundant. This patch also changes dev_remove() function prototype (and all it's callers, where it' requied) by adding network namespace pointer parameter, which is used to discover proper blocklayout pipe for rpc_queue_upcall() call.
