cryptodev: Fix cryptodev_builtin_cleanup() error API violation 

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

cryptodev_builtin_cleanup() passes @errp to
cryptodev_builtin_sym_close_session() in a loop.  Harmless, because
cryptodev_builtin_sym_close_session() can't actually fail.  Fix it
anyway.
