regulator: Fix check of unsigned return value and transmit errors in wm831x_gp_ldo_get_mode()

If ret is unsigned, the checks for negative wm831x_reg_read() return values
are wrong. The error value should be transmitted to its caller, e.g.
wm831x_gp_ldo_get_status() which tests for a negative return value.
