	src/sys/kern: kern_ktrace.c
	src/sys/nfs: nfs_bio.c

Log Message:
Fix of panic that was introduced since ktrace-lwp branch was merged. The
shortcut to the process of the passed lwp paniced the kernel since lwp
could/can be passwd as NULL in VOP_WRITE().

This was happening when ktracing to NFS. The function ktrwrite() set the
uio_lwp to NULL and then calls VOP_WRITE() with this argument. nfs_write()
then accessed lwp *l->l_proc wich paniced.

Thanks to David Laight for his help on tracking it down.
