  x86/sgx/virt: implement SGX_IOC_VEPC_REMOVE ioctl (2021-10-22 08:32:12 -0700)

----------------------------------------------------------------
Add a SGX_IOC_VEPC_REMOVE ioctl to the /dev/sgx_vepc virt interface with
which EPC pages can be put back into their uninitialized state without
having to reopen /dev/sgx_vepc, which could not be possible anymore
after startup due to security policies.
