CVE-2021-47642

Coverity complains of a possible buffer overflow. However, given the 'static' scope of nvidiasetupi2c_bus() it looks like that can't happen after examiniing the call sites.

CID 19036 (#1 of 1): Copy into fixed size buffer (STRINGOVERFLOW) 1. fixedsizedest: You might overrun the 48-character fixed-size string chan->adapter.name by copying name without checking the length. 2. parameteras_source: Note: This defect has an elevated risk because the source argument is a parameter of the current function. 89 strcpy(chan->adapter.name, name);

Fix this warning by using strscpy() which will silence the warning and prevent any future buffer overflows should the names used to identify the channel become much longer.
