Konstantin Belousov 1fac7d7f35 Lock the new map in vmspace_fork(). The newly allocated map should not 
be accessible outside vmspace_fork() yet, but locking it would satisfy
the protocol of the vm_map_entry_link() and other functions called
from vmspace_fork().

Use trylock that is supposedly cannot fail, to silence WITNESS warning
of the nested acquisition of the sx lock with the same name.
