Modified Files:
        src/sys/rump/librump/rumpkern: vm.c

Log Message:
Instead of causing a catastrophic failure when uvm_loanuobjpages()
is called, just pretend it hit a wired page and return EBUSY.  This
should cause callers to use a non-loaning access path instead.

Fixes file read path of stock nfs kernel module (previously it was
easy to just frob the nfsd_use_loan boolean into the other position
by simple value assingment, but now that nfsserver can be autoloaded
at runtime into the rump kernel, that approach is a little more
challenging since the variable isn't available in application
linkage.  yes, things like adding a sysctl for the variable would
work, but now everything works out-of-the-box).
