NFSD, VFS: Remove dead code in nfsd_rename()
Currently we have the following code in fs/nfsd/vfs.c::nfsd_rename() : ... host_err = nfsd_break_lease(odentry->d_inode); if (host_err) goto out_drop_write; if (ndentry->d_inode) { host_err = nfsd_break_lease(ndentry->d_inode); if (host_err) goto out_drop_write; } if (host_err) goto out_drop_write; ... 'host_err' is guaranteed to be 0 by the time we test 'ndentry->d_inode'. If 'host_err' becomes != 0 inside the 'if' statement, then we goto 'out_drop_write'. So, after the 'if' statement there is no way that 'host_err' can be anything but 0, so the test afterwards is just dead code. This patch removes the dead code.
