kernel - Refactor inum stat data for sockets

* Assign a dummy inode number to all sockets. We previously were
only assigning a dummy inode number to unix domain sockets. Use
the new pcpu facility and store the inum in the socket structure.

* Rip out the old inode number assigner for unix domain sockets, it
was using an atomic_fetchadd_long() on a global variable, introducing
unnecessary SMP stalls. And it was specific to unix domain sockets.
The new facility is generic to all sockets and uses a pcpu data
structure.
