x86/purgatory: Return bool from verify_sha256_digest()

Browse source

Change the function's return type from 'int' to 'bool' and return the result
of memcmp() directly to simplify the code.  While at it, cast ->start to
const u8 * to better match the expected type.

Also inline the verify_sha256_digest() check and remove the redundant
local 'ret' variable in purgatory().

No change in functionality expected.
