Remove the pseudocode documentation of __vdso_sgx_enter_enclave().  The
assembly itself needs to be cleaned up to be easily understood without
pseudocode, and the extra documentation adds maintenance overhead.

Only the prototype is needed to coerce kernel-doc into parsing the
function comment, so that isn't lost either.
