drivers/usb/class/cdc-acm.c: clear dangling pointer
commit e7c8e8605d0bafc705ff27f9da98a1668427cc0f upstream.
On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself. Elsewhere, operations including
memcpy and kfree are performed on the country_code field. The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.
