serial: mctrl_gpio: Fix build warnings
Fix the following build warnings:
drivers/tty/serial/serial_mctrl_gpio.c: In function 'mctrl_gpio_init':
drivers/tty/serial/serial_mctrl_gpio.c:110:4: warning: return makes pointer from integer without a cast
return PTR_ERR(gpios->gpio[i]);
^
/home/build/work/batch/drivers/tty/serial/serial_mctrl_gpio.c:90:6: warning: unused variable 'err' [-Wunused-variable]
int err;
^
Return ERR_CAST and remove the unused 'err' variable to fix them.
