wifi: rtw89: usb: fix leak in rtw89_usb_write_port()

Browse source

[ Upstream commit 7543818e97 ]

When there is an attempt to write data and RTW89_FLAG_UNPLUGGED is set,
this means device is disconnected and no urb is submitted.  Return
appropriate error code to the caller to properly free the allocated
resources.
