Conrad Meyer 9da903e5d3 Unlocked getblk: Fix new false-positive assertion
A free buf's lock may be held (temporarily) due to unlocked lookup, so
buf_alloc() must acquire it without LK_NOWAIT.  The unlocked getblk path
should unlock it promptly once it realizes the identity does not match
the buffer it was searching for.
