David Gibson 82a93a1d30 spapr: Remove 'awaiting_allocation' DRC flag 
The awaiting_allocation flag in the DRC was introduced by aab9913
"spapr_drc: Prevent detach racing against attach for CPU DR", allegedly to
prevent a guest crash on racing attach and detach.  Except.. information
from the BZ actually suggests a qemu crash, not a guest crash.  And there
shouldn't be a problem here anyway: if the guest has already moved the DRC
away from UNUSABLE state, the detach would already be deferred, and if it
hadn't it should be safe to detach it (the guest should fail gracefully
when it attempts to change the allocation state).

I think this was probably just a bandaid for some other problem in the
state management.  So, remove awaiting_allocation and associated code.
