USB: serial: f81534: detect errors from f81534_logic_to_phy_port()
With gcc 4.1.2: drivers/usb/serial/f81534.c: In function ‘f81534_port_probe’: drivers/usb/serial/f81534.c:1250: warning: comparison is always false due to limited range of data type f81534_logic_to_phy_port() may return a negative error value, which is ignored by assigning it to u8 f81534_port_private.phy_num. Use an intermediate variable of type int to fix this. While at it, forward the actual error code instead of converting it to -ENODEV, and drop the useless check for F81534_NUM_PORT, as the callee always returns a valid port number in case of success.
