Do not preallocate the asid, wait until it is allcoated in pmap_setttb()
Simplifies the code by only having one location that does the asid
allocation.
There is no need to allocate the ASID direclty in pmap_activate as
the code in pmap setttb will do that allocation so this code is just
duplication that could potentially cause a race in the future.
