regulator: tps65185: handle gpiod_get_value_cansleep() error returns

tps65185_vposneg_enable() evaluated:
  if (gpiod_get_value_cansleep(data->pgood_gpio) != 1)
      return -ETIMEDOUT;

gpiod_get_value_cansleep() returns 1 if active, 0 if inactive, and a
negative error code (e.g. -EIO or -EINVAL) on failure. Evaluating != 1
treats a negative error code as non-equal, swallowing GPIO read errors and
masking them as -ETIMEDOUT.

Fix this by capturing the return value of gpiod_get_value_cansleep(). If
it returns a negative error code, propagate that error immediately; if
it returns 0 (inactive), return -ETIMEDOUT.
