hw/usb/hcd-dwc2: Handle invalid address access in read and write functions
This commit modifies the dwc2_hsotg_read() and dwc2_hsotg_write() functions
to handle invalid address access gracefully. Instead of using
g_assert_not_reached(), which causes the program to abort, the functions
now log an error message and return a default value for reads or do
nothing for writes.
This change prevents the program from aborting and provides clear log
messages indicating when an invalid memory address is accessed.
Reproducer:
