wifi: rtl8xxxu: gen2: Fix mistake in path B IQ calibration 



[ Upstream commit e963a19c64ac0d2f8785d36a27391abd91ac77aa ]

Found by comparing with the vendor driver. Currently this affects
only the RTL8192EU, which is the only gen2 chip with 2 TX paths
supported by this driver. It's unclear what kind of effect the
mistake had in practice, since I don't have any RTL8192EU devices
to test it.

Fixes: e1547c53 ("rtl8xxxu: First stab at adding IQK calibration for 8723bu parts")
