[PATCH] NFS: fix client oops when debugging is on
nfs_readpage_release() causes an oops while accessing a file with NFS
debugging turned on (echo 32767 > /proc/sys/sunrpc/nfs_debug) and a kernel
built with CONFIG_DEBUG_SLAB.
This patch moves the debugging statement above nfs_release_request() to
avoid accessing freed memory.
