AVR: avr.cc - Drop a superfluous sub-condition in avr_out_compare.

In avr.cc::avr_out_compare() there is this condition:

  if (n_bytes == 4
      && eqne_p
      && AVR_HAVE_ADIW
      && REGNO (xreg) >= REG_22
      && (xval == const0_rtx
	  || (IN_RANGE (avr_int16 (xval, 2), 0, 63)
	      && eqne_p
	      && reg_unused_after (insn, xreg))))

where the 2nd sub-expression "&& eqne_p" is superfluous.

gcc/
	* config/avr/avr.cc (avr_out_compare): Drop superfluous sub-condition.
