extcon: ptn5150: Do not print error during probe if nothing is attached
The commit 85256f611f66 ("extcon: ptn5150: Check current USB mode when probing") reused code for checking CC status register in the probe path to determine what is initially connected. However if nothing is connected, the CC status register will have 0x0 value and print an error message: ptn5150 1-003d: Unknown Port status : 0 This is not an error. Also any other unknown port status values are not really errors but unhandled cases.
