Haitao Huang 81fa6fd13b x86/sgx: Handle VA page allocation failure for EAUG on PF. 
VM_FAULT_NOPAGE is expected behaviour for -EBUSY failure path, when
augmenting a page, as this means that the reclaimer thread has been
triggered, and the intention is just to round-trip in ring-3, and
retry with a new page fault.
