[PATCH 1/3] cmd: optee_rpmb: sanitize TEE_ERROR -> E* translations

Do not translate both OUT_OF_MEMORY and STORAGE_NO_SPACE to -ENOSPC;
we have -ENOMEM which is more fitting for the former.

Similarly, -ENOENT is a better match for ITEM_NOT_FOUND than "some IO
went wrong".

None of the callers currently care about the actual error code, so
this makes no functional change, but we will add special handling of
the -ENOSPC in a later patch.
