AVR: ad target/84211 - Fix a build failure on some hosts.

	This fixes a build failure on hosts where HARD_REG_SET is not a scalar.
	The issue was introduced with the patch for PR84211 in r15-5415.
	PR target/84211
gcc/
	* config/avr/avr-passes.cc (memento_t::apply_insn1): Don't
	use operator &= on memento_t.known but on memento_t itself.
