[issue2154] vkernel copyout() doesn't return EFAULT on error

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

New submission from Venkatesh Srinivas <vsrinivas@dragonflybsd.org>:

copyout() is documented as returning 0 or EFAULT; the vkernel version doesn't do
so, it returns a VM error code, which needs translating.
