- change the state to SPLICE_EXCEPTION to allow so_unsplice() to work
to cleanup failed splices (fixes socket reference leak)
- NULL out sp->dst when unsplicing from so_splice() before so2 has been
been referenced.
- Deal with a null sp->dst / so2 in so_unsplice
- Fix asserts that talked about sp->state == SPLICE_INIT; that state
is not possible here.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
