ghes_read_estatus() reads the record address, then the record's header, then performs some sanity checks before reading the records into the provided estatus buffer. To provide this estatus buffer the caller must know the size of the records in advance, or always provide a worst-case sized buffer as happens today for the non-NMI notifications. Add a function to peek at the record's header to find the size. This will let the NMI path allocate the right amount of memory before reading the records, instead of using the worst-case size, and having to copy the records. Split ghes_read_estatus() to create __ghes_peek_estatus() which returns the address and size of the CPER records.
