Modified Files:
        src/sys/uvm: uvm_amap.c uvm_io.c

Log Message:
the previous fix for PR 55366 in uvm_amap.c 1.124 was incomplete:
 - amap_adjref_anons() must also ignore AMAP_REFALL when updating
   the ppref, not just when deciding whether or not to initialize ppref.
 - UVM_EXTRACT_QREF relies on AMAP_REFALL to work properly,
   and since we can't use AMAP_REFALL then we can't use QREF either.
