Remove the "struct lwp *" argument from all VFS and VOP interfaces.

The general trend is to remove it from all kernel interfaces and
this is a start. In case the calling lwp is desired, curlwp should
be used.

This fixes a '"panic: malloc: out of space in kmem_map" when it's not

to fix PR/35587 as well.
Looks/seems fine to me from chuq and yamt. Thanks.
