vm_page.c: fix a deadlock when running with smp enabled
the call vm_page_seg_pull_cache_page() return an vm_page (src) with his
object being locked, as we don’t unlock before doing the vm_page_insert,
it is still lock there, and so trying to relock it cause a deadlock.
Replace this lock by an assert.
This case was not seen as for non-smp locking is a no-op.
