backend-drm: Initialize bo_fd

Browse source 
On some aarch64 platforms with GCC13 we're seeing:

../../../weston-14-new/libweston/backend-drm/fb.c:152:15: warning: 'bo_fd' may be used uninitialized [-Wmaybe-uninitialized]
  152 |         ret = drmPrimeFDToHandle(fb->fd, bo_fd, &handle);
      |               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../../weston-14-new/libweston/backend-drm/fb.c: In function 'drm_fb_addfb':
../../../weston-14-new/libweston/backend-drm/fb.c:117:13: note: 'bo_fd' was declared here
  117 |         int bo_fd;

Just initialize it to avoid trigger the warning.
