Kirk McKusick 69166928c7 This is an additional and hopefully final fix for bug report 230962.
This bug was introduced with the change to use softdep_bp_to_mp()
in January 2018 changes -r327723 and -r327821. The softdep_bp_to_mp()
function failed to include VSOCK as one of the valid cases.

Although local-domain sockets do not allocate blocks in the filesystem,
they will allocate blocks if they use extended attributes (such as
ACLs). Thus, softdep_bp_to_mp() needs to return a non-NULL mount
pointer when presented with a socket vnode so that the soft updates
write complete will properly process the soft updates structures
associated with the extended attribute blocks. It was the failure
to process these soft updates structures, thus leaving them hanging
off the buffer, which lead to the "panic: softdep_deallocate_dependencies:
dangling deps" when trying to clean up the buffer after it was written.
