Subject: [PATCH V2 02/15] x86/sgx: Rename fallback labels in sgx_init()

From: Jarkko Sakkinen <jarkko@kernel.org>

It's hard to add new content to this function because it is time
consuming to match fallback and its cause. Rename labels in a way
that the name of error label refers to the site where failure
happened. This way it is easier to keep on track what is going
on.
