Subject: [PATCH v9 1/6] x86/sgx: Convert sgx_(vepc_)open to __sgx_(vepc_)open

In order to introduce the counting of active sgx users on top
of clean functions that allocate vepc structures, covert existing
sgx_(vepc_)open to __sgx_(vepc_)open. Later patch will introduce the
top level wrappers that manage the usage count.

No functional change intended in this patch.
