Christian S.J. Peron 417ab24f78 Check to see if we wired the user-supplied buffers in SYSCTL_OUT, if
the buffer has not been wired and we are holding any non-sleep-able locks,
drop a witness warning. If the buffer has not been wired, it is possible
that the writing of the data can sleep, especially if the page is not in
memory. This can result in a number of different locking issues, including
dead locks.
