[PATCH v2] usb: dwc3: Fix crash on fastboot exit due to incorrect memory free

[Balaji Selvanathan]

The dwc3_free_one_event_buffer() function incorrectly called free()
on event buffer structures allocated with devm_kzalloc(). This
caused heap corruption and a synchronous abort when exiting
fastboot mode via "fastboot continue".

Device-managed memory is automatically freed when the device is
removed, so manual deallocation causes the heap allocator to access
corrupted metadata.

Fixes: 884b10e86a05 ("usb: dwc3: core: fix memory leaks in event buffer cleanup")
