ALSA: usb-audio: simplify mixer control name handling

Browse source

In get_term_name(), remove hard-coded return values and a strlen() call,
and return the number of bytes copied by strscpy() directly.

Since get_term_name() may now return -E2BIG on string truncation, check
name_len < 0 and return early from get_connector_control_name() if
needed. Also replace strlcat() with strscpy().

Other get_term_name() callers only check the return value for non-zero
and are not affected by this change.
