Revert previous: unref of amap outside of the KERNEL_LOCK().

This change introduced or exposed a leak of anons which result in system
freezes.

anton@ observed a high number of INUSE for anonpl and semarie@ saw multiple
processes waiting in the fault handler on "flt_noramX" probably the one
related to allocating an anon.
