[issue1861] panic via kprintf (lockmgr called in a hard section)

["Venkatesh Srinivas \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Venkatesh Srinivas <me@endeavour.zapto.org>:

kbd_ioctl takes a lockmgr lock; kprintf calls kvcprintf, which enters a hard
section if it is calling kputchar (it is via kprintf). kbd_ioctl is called via
cnputc, from kputchar. This causes a panic.
