rtlwifi/rtl8192de: remove redundant else if check

The else if check condition checks for the opposite of the
if check, hence the else if check is redundant and can be
replaced with a simple else:

if (rtlpriv->rtlhal.macphymode == SINGLEMAC_SINGLEPHY) {
	..
} else if (rtlpriv->rtlhal.macphymode != SINGLEMAC_SINGLEPHY) {
	..
}

replaced with:

if (rtlpriv->rtlhal.macphymode == SINGLEMAC_SINGLEPHY) {
	..
} else {
	..
}
