Fix assert in PowerPC pmaps after introduction of object busy.
The VM_PAGE_OBJECT_BUSY_ASSERT() in pmap_enter() implementation should be only asserted when the code is executed as result of pmap_enter(), not when the same code is entered from e.g. pmap_enter_quick(). This is relevant for all PowerPC pmap variants, because mmu_*_enter() is used as the backend, and assert is located there. Add a PowerPC private pmap_enter() PMAP_ENTER_QUICK_LOCKED flag to indicate that the call is not from pmap_enter(). For non-quick-locked calls, assert that the object is locked.
