pinctrl: mt7622: Fix probe fail by misuse the selector
[ Upstream commit 238262af08a20e5f1932fcf606b8b84370ac8b77 ] After the commit acf137951367 ("pinctrl: core: Return selector to the pinctrl driver") and the commit 47f1242d19c3 ("pinctrl: pinmux: Return selector to the pinctrl driver"), it's necessary to add the fixes needed for the pin controller drivers to use the appropriate returned selector for a negative error number returned in case of the fail at these functions. Otherwise, the driver would have a failed probe and that causes boot message cannot correctly output and devices fail to acquire their own pins.
