CVE-2025-39801: usb: dwc3: Remove WARN_ON for device endpoint command timeouts

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: Remove WARNON for device endpoint command timeouts

This commit addresses a rarely observed endpoint command timeout which causes kernel panic due to warn when 'paniconwarn' is enabled and unnecessary call trace prints when 'paniconwarn' is disabled. It is seen during fast software-controlled connect/disconnect testcases. The following is one such endpoint command timeout that we observed:

1. Connect ======= ->dwc3threadinterrupt ->dwc3ep0interrupt ->configfscompositesetup ->compositesetup ->usbepqueue ->dwc3gadgetep0queue ->dwc3gadgetep0queue ->dwc3ep0docontroldata ->dwc3sendgadgetepcmd

2. Disconnect ========== ->dwc3threadinterrupt ->dwc3gadgetdisconnectinterrupt ->dwc3ep0resetstate ->dwc3ep0endcontroldata ->dwc3sendgadgetepcmd

In the issue scenario, in Exynos platforms, we observed that control transfers for the previous connect have not yet been completed and end transfer command sent as a part of the disconnect sequence and processing of USBENDPOINTHALT feature request from the host timeout. This maybe an expected scenario since the controller is processing EP commands sent as a part of the previous connect. It maybe better to remove WARNON in all places where device endpoint commands are sent to avoid unnecessary kernel panic due to warn.
