lib/igt_debugfs: Update documentation and cleanup
The documentation was lying. The igt_crc_to_string() is threadsafe and
does not return a pointer to an internal buffer.
Actually the caller is responsible for the memory that is allocated (and
they are for all the current cases), so let's put that in the doc too.
While I was at it I got rid of strdup() in favor of an early allocation.
