Brian Gianforcaro 1415b2cfc3 Kernel: Do not allocate AnonymousVMObject's under spin lock 
Spinlocks guard short regions, with hopefully no other locks being taken
in the process. Violating constraints usually had detrimental effects on
platform stability as well as performance and scalability. Allocating
memory takes it own locks, and can in some cases even allocate new
regions, and thus violates these tenants.

Move the AnonymousVMObject creation outside of the spinlock as
creation does not modify any shared state.
