fbdev: radeon: fix potential memory leak in radeonfb_pci_register()

Browse Source 
The function radeonfb_pci_register() allocates memory for modelist
(by calling radeon_check_modes() which calls fb_add_videomode()).
The memory is appended to info->modelist, but is not freed in subsequent
error paths. Fix this by calling fb_destroy_modelist().
