Revert "cdc_subset: deal with a device that needs reset for timeout"
This reverts commit 20fbe3ae990fd54fc7d1f889d61958bc8b38f254.
As reported by Stephen Rothwell, it causes compile failures in certain
configurations:
drivers/net/usb/cdc_subset.c:360:15: error: 'dummy_prereset' undeclared here (not in a function)
.pre_reset = dummy_prereset,
^
drivers/net/usb/cdc_subset.c:361:16: error: 'dummy_postreset' undeclared here (not in a function)
.post_reset = dummy_postreset,
