Pekka Paalanen 03ac7b1821 backend/native: Share drmModeAddFB code
With all the three paths this is quite a handful of code, and it was mostly
duplicated in two places. A follow-up patch would need to introduce a third
copy of it. Therefore move the code into a helper function.

There are two behavioral changes:

- The format error now prints the string code as well, because it is easy to
  read.

- The g_debug() in init_dumb_fb() is removed. Did not seem useful.
