Ladislav Michl c987694755 video: udlfb: Fix read EDID timeout
While usb_control_msg function expects timeout in miliseconds, a value
of HZ is used. Replace it with USB_CTRL_GET_TIMEOUT and also fix error
message which looks like:
udlfb: Read EDID byte 78 failed err ffffff92
as error is either negative errno or number of bytes transferred use %d
format specifier.

Returned EDID is in second byte, so return error when less than two bytes
are received.

Fixes: 18dffdf891 ("staging: udlfb: enhance EDID and mode handling support")
