net: dsa: Simplify 'dsa_tag_protocol_to_str()'
There is no point in preparing the module name in a buffer. The format
string can be passed diectly to 'request_module()'.
This axes a few lines of code and cleans a few things:
- max len for a driver name is MODULE_NAME_LEN wich is ~ 60 chars,
not 128. It would be down-sized in 'request_module()'
- we should pass the total size of the buffer to 'snprintf()', not the
size minus 1
