Documentation: Fix size parameter for snprintf
cppcheck reports this error:
Documentation/laptops/hpfall.c:33]: (error)
Dangerous usage of 'devname' (strncpy doesn't always 0-terminate it)
The terminating '\0' is needed for the global char array unload_heads_path,
so never write the last array entry (which is initially '\0').
