nfs_nfsdsocket.c: All Copy and Clone across file systems
For some server file system types, such as ZFS, a Copy/Clone
operation can be done across file systems of the same file
system type.
As such, this patch allows the Copy/Clone to be attempted
when the file handles are for files on different file systems.
This fixes a problem for exported ZFS file systems when a
copy_files on file_range(2) between file systems in the same
NFSv4 mount is attempted.
