Ryan Libby 9c975a0d90 pbuf_ctor(): Stop using LK_NOWAIT, use LK_NOWITNESS
The LK_NOWAIT was added to suppress a witness warning, but LK_NOWITNESS
is more what we mean.  This makes pbuf_ctor() more consistent with
buf_alloc(), although, unlike buf_alloc(), for pbuf there should not be
any danger of a wild locker relying on the type stability of the buf to
attempt a lock.  That is, this is essentially cosmetic.

Relevant history:
 - 531f8cfea0 Use dedicated lock name for pbufs
 - 5875b94c74 buf_alloc(): lock the buffer with LK_NOWAIT
 - c9e023541a pbuf_ctor(): lock the buffer with LK_NOWAIT
 - 1fb00c8f10 buf_alloc(): Stop using LK_NOWAIT, use LK_NOWITNESS

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.
