Subject: [PATCH v2] usb: common: usb-conn-gpio: Simplify some error message

dev_err_probe() already prints the error code in a human readable way, so
there is no need to duplicate it as a numerical value at the end of the
message.

Fixes: ddaf0d6dc467 ("usb: common: usb-conn-gpio: use dev_err_probe() to print log")
Signed-off-by: Christophe JAILLET <christophe.jaillet@...adoo.fr>

Change in v2:
  * keep the message on the same line of dev_err_probe() because the line is
    still < 100 char   [Chunfeng Yun <chunfeng.yun@...iatek.com>]
